phX est une demo Amstrad CPC de Condense, cinq ans de travail : commencée en 2013, terminée en mars 2018 et présentée à la Revision 2018, à Sarrebruck, où elle a pris la deuxième place de la compétition oldskool demo, puis, un an plus tard, une nomination aux Meteoriks dans la catégorie Best Low-End Production. Code de NoRecess, visuels de Ced, audio de Factor6, disc loader d’Arnoldemu ; le code source a été rendu public une semaine après la sortie, mais le dépôt qui l’hébergeait n’est plus en ligne. Comment chaque partie a été construite est raconté, page après page, dans le making-of plus bas.

Le making-of
Trente-quatre pages, écrites en mars 2018 et livrées dans l’archive de sortie : comment chaque partie de la demo a été construite, dans l’ordre où elle l’a été, avec les versions ratées en chemin. Chaque page s’ouvre en grand, et l’original peut être téléchargé entier — le making-of en PDF.
Il s’ouvre sur un avertissement qui mérite d’être répété ici : c’est un making-of, et il dévoile presque tous les écrans de la demo. Regardez phX d’abord.

At some point it’s hard to tell if you’re watching a CPC prod or an ATARI ST intro… amazing work.
— fra, 2018-04-01 · rulez
Very nice!
— Mystra, 2018-04-01 · rulez
perfect gfx, damned fast and synced - thank you guys! YouTube
— ded^RMDA, 2018-04-01 · rulez
Welcome back to demoparties! Great release, but I was a bit let down this didn’t really measure up with your previous demo which is still one of my favorites on any 8-bit platform. Still, your amazing skill with color choices and pixel art is in full show here.
— visy, 2018-04-01 · rulez
Awesome pace and sync. Great!
— Kylearan, 2018-04-01 · rulez
Yay! Expecting this to be released for some time now - definitely worth the wait :) Congrats guys!

A complete color inferno! One of my favorites in this compo.
— JTZ, 2018-04-01 · rulez
A very generous demo that contains lots of very high quality effects, moving and flowing on smoothly at a fast pace. Very nice gfx and music too. This is an instant thumb up. Kudos to you guys!
— RetroVM, 2018-04-01 · rulez
The oldschool is vibrant and strong here!
— CiH, 2018-04-01 · rulez

Bein voila, moi qui t’avais reproché de ne faire que du soft, je n’ai plus qu’à la fermer ^^ Superbe prod !!! C’est du grand art sur tout les niveaux. Demo qui ira direct sur le podium des meilleurs démos cpc sans aucun soucis :)
— BDCIron, 2018-04-01 · rulez
Way too colorful for my taste, but I love how effortlessly it flows. A masterpiece for the CPC for sure.
— Preacher, 2018-04-01 · rulez
amazing! and probably my fav prod of this years revision…
— RufUsul, 2018-04-01 · rulez
Great show with awesome gfx.
— gaspode, 2018-04-01 · rulez
Super solid and fun prod! A joy to watch in the compo :)
— ferris, 2018-04-01 · rulez
Outstanding performance! Quite different than your previous soft rendering demos, this time fullscreen smooth hardware stuff and also with great flow/pace. Thanks also for the making off.
— Optimus, 2018-04-01 · rulez
Oh my god, loved this one. Sadly it competes against our entry in the same compo, but there is no shame loosing to a demo as polished like this. Great work.
— Ramon B5, 2018-04-01 · rulez
Incredible work, congrats guys!
— Soundy, 2018-04-01 · rulez
Very good job! Ofcourse I’d have quite a few comments/questions I would like to discuss on the cpc demoscene related website, if there were one! :P
— rexbeng/PA, 2018-04-01 · rulez
phX was an amazing experience for us, it’s so nice to gather such positive feedback after working for years in the shadow… So now some facts about the demo: - a making-of is available ! please have a look above for the link. This is an high-level overview, 30+ pages .pdf format; if you really liked the prod I strongly suggest you to extend the experience with this lecture! - 1 coder - 5 years of development.... can’t believe it’s finally released - traveled from Canada to Germany to present this at party-place ! - Condense did not present anything at parties for 15 years, now it’s fixed :) Thank you all and feel free to contact us for info etc.
— norecess, 2018-04-01
Huge and dynamic “in-your-face” colourfull explosion of eye bursting awesomness. Love the pixel arts, the dithered palette, the cube, the fast paced smoothness of quite frankly everything. don’t have time to get bored and all scrolltexts are actually easy to read. Music was a nod to Batman Begins at some points and hope this demo will have the same destiny. Thumbs and dick up !!!
— MacDeath, 2018-04-01 · rulez
Fucking awesome :D
— psonice, 2018-04-01 · rulez
What everyone before me said.. and: awesome!
— BSC, 2018-04-01 · rulez
Good one.. Jocking. I didn’t read the nfo before running it, just I saw that incredible screenshot, I say myself, go find a CPC, select that new logo with CRTC 1 and make a coffee. All this colorfull demo in perfect fullscreen on the CTM-644-2 just amaze. The music as well, I loved the whistle part a lot.. Fantastic demo. Did you saw that plasma?? CPC FUCKING RULEZ!!
— Buckethead, 2018-04-01 · rulez
Awesome!
— mr_lou, 2018-04-01 · rulez
I was about to say that Condense had released stuff less than 15 years ago, but when I checked the released date for Barbitoric (in which Jylam participated - thus the Condense logo), it was indeed in 2003 :D Nice graphics :)
— Dbug, 2018-04-01 · rulez
Yeah!
— baah, 2018-04-01 · rulez
Very happy to see this comeback, Norecess progressed so much with this great demo.I must say i’m impressed =)
— fano, 2018-04-01 · rulez

Entering Olymp with this demo! Words can’t describe my feelings after watching this!
— Bobic, 2018-04-01 · rulez
Well done arnaud
— nytrik, 2018-04-01 · rulez
As a ZX Speccy fan, I must admit, this blow my socks off. Visuals and effects are outstanding. I am sorry for the music which I found an mediocre AY stuff, heared many times before.
— Trauma Zero, 2018-04-01 · rulez
Very rich demo, lot of fx, lot of parts, everything clean and smooth. Gratz! Just a bit too much rasters for me. ;)
— OffseT, 2018-04-01 · rulez
Great great prod!
— Joseman, 2018-04-02 · rulez
Kudos CPC!
— analone, 2018-04-02 · rulez
If this doesn’t win the compo, I fress a Besen.

Thank you. Your demo guys means so much.
— Overflow, 2018-04-02 · rulez
Back to the futur, raster, plasma , I like it tttt And You warmed the heart of my cpc
— mic, 2018-04-02 · rulez
Fucking awesome! But still not a Batman killer! :]
— ham, 2018-04-02 · rulez
Really good demo, some clever effects and sublimed by a not less impressive pixel art . Is there a wink at batman forever on the music ?? ^^
— TOUKO, 2018-04-02 · rulez
A big amount of work and effects. Nothing to say more about the technical level, it was what I excepted from No Recess! Huge progress in CRTC’s technics! Imho rasters are sometimes too much and the Face Hugger’s balls effect is not so interesting (or at least too long). But phX is a master-piece! Well done, guys!
— EliotBenediction, 2018-04-02 · rulez
Great effects, very colourful, and nice music and overall design!
— Scali, 2018-04-02 · rulez
Congrats NoRecess !!! GReat prod (I told you that before) and awesome grit during those 5 years … Can’t wait to have your live feedback and pictures !! :)
— wiss1, 2018-04-02 · rulez
Awesome!
— TUMO, 2018-04-02 · rulez
that is awesome!!! :D don’t know that Amstrad with CRTC are able to do those things!!!
— seban, 2018-04-02 · rulez
And that great music from Factor6! This is marvellous!!!
— seban, 2018-04-02
Nice show! CeD’s pictures are very beautiful!
— toms, 2018-04-02 · rulez
good job
— med, 2018-04-02 · rulez
Great demo! Lots of effects that never have time to get boring because of the perfect flow. Top graphics too obviously.

In french: J’ai regardé le streaming :) A l’applaudimètre comme le disait Roudoudou, c’est clair que tu étais le numéro 1.
— cmpcpc, 2018-04-03 · rulez
Congratulation to Condence, your skill is now +10. Level up! An amazing production that deserved the best place without any doubt.
— TotO, 2018-04-03 · rulez
Great code and art!
— micdune, 2018-04-03 · rulez
Awesome production Norecess! And you have also put soooooo much time into it - I guess I wouldn’t have the stamina to bring such a project to the end. It was also great to meet you on the Revision. A big thumbs up from me :-)!!!!
— Octoate, 2018-04-03 · rulez
Incredible work! I was so sure it would be #1! But it’s number one in my heart at least :) Cant wait for the next one. Hope it wont take 5 years hehehe.
— alkama, 2018-04-03 · rulez
another CPC epic, nuff said.
— decca, 2018-04-03 · rulez
Great!
— keops, 2018-04-03 · rulez
Great!
— bitl, 2018-04-03 · rulez
I admit I never thought your demo would be as good as it is! I like the in-your-face effects, full screen, with a bit of an old-school touch with these rasters. The design is, as always with Ced, speechless. A great achievement.
— Targhan, 2018-04-03 · rulez
I agree with Targhoune. A big work, 50hz, and good direction… No Recess still rising ;)
— Hicks, 2018-04-03 · rulez
Super impressive work! particular remarks: stunning graphics giant shaded rotating cube perceived e-guitar sounds in the epsilon part Thanx for the outstanding information in the nfo and the making-of! It was so fabulous that we’ve met at Revision this year!
— dOc.K, 2018-04-04 · rulez
great to see more CPC high quality demos being released!
— psenough, 2018-04-04 · rulez

Yes.
— Charlie, 2018-04-05 · rulez
Amazing ! If i known we could do stuff like this on CPC i hadn’t be so hard with mine ! Big up to you norecess, nice i did the travel back to the airport with you !
— RaHoW, 2018-04-05 · rulez
Thank you, merci and dĕkuji for this fantastic release. Great job!
— villain, 2018-04-05 · rulez
Awesome !!! Smart code, and superb graphics (like a C64 on a double dose of steroids!!!) I’m not crazy about AY music (on any platform), but this music fit the visuals nicely. 100% thumb up :) Maybe this should have won the compo!
— DanLemon, 2018-04-05 · rulez
Very Good!
— Batman/BG, 2018-04-05 · rulez
New hardware effects on the CPC, good artwork, fast pace… It should have won the first place instead of “We Come in Peace”, don’t you think?
— cngsoft, 2018-04-06 · rulez
Very polished and impressive demo. I am not a super fan of abusing of rasters, but most effects are really nice (especially in the last part) and the job to do that must have been huge. You can be proud of the result !
— tometjerry, 2018-04-06 · rulez
nice one… colorful… i like that shifting of the efx so more than one is visible… parallax bars are looking a bit too small steps in animation…anyway thumpy ;)
— ultra, 2018-04-06 · rulez
So so.
— AntDude, 2018-04-07
Awesome! Great music, nice and varied effects, excellent fullscreen pictures and really nice color schemes.
— StingRay, 2018-04-07 · rulez
Besides awesome demo props for making a detailed note, every oldschool/newschool demo should have one.
— Nitro/Black Sun, 2018-04-07 · rulez
Very nice demo, good looking pictures and effects.
— 4pLaY, 2018-04-07 · rulez
FYI, Source-code of the demo were made available here.
— norecess, 2018-04-08
For me the most kickass release on the party (and that’s with some great competition)! Fave moment is the up to 3-effect-switching with the checkerboard and Alcatraz bars, but it’s the complete barrage and music that makes it so swesome :)
— Photon, 2018-04-08 · rulez
Kinda childishly cute but similarly also naivistic and not in a good way.
— noby, 2018-04-08
You should be very proud of this demo, I really enjoyed watching it. Some really cool fx, synced well with the music. Ced is on fire too :-). Guys please never stop making demos for the CPC. I love all of your demos....Phortem is one of my favourites
— __sice, 2018-04-08 · rulez

Cool demo. short and many effects.
— Supersly, 2018-04-13 · rulez
Normally i´d counter your accidental upvote, but sorry, this is just way too good, i have to thumb it up properly! ;) Voting oneself up after 5 years of work ain´t a bad thing to do afterall! :) Nothing left to say others didn´t say yet! ;) PotcFdk: How did your Besen taste? :p
— ɧ4ɾɗվ., 2018-04-14 · rulez
Very good demo and i enjoyed watching it! Some of the pics inside the demo are a real eye-catcher. There are really some good prods came out on Amstrad-CPC in last time. Interesting!!!

Awesome colorful demo, with an impressive technical level. Worthy of the first place in Revision imo.

Nice Amstrad CPC demo had forgotten to thumb this up
— Queen_Luna, 2018-11-04 · rulez
rocks!
— skarab, 2018-11-04 · rulez
Rocks CPC hard, could not look away.
— Claw, 2019-01-05 · rulez
Excellent demo. In truth it is the absolutely worst kind of oldschool imaginable (at heart), however, the idea to zoom into every single effect pays off and gives it a new, very modern quality.
— introspec, 2019-01-05 · rulez
Nice oldskool rasterised colours style, but indeed particularly finely scripted and synched.
— Dma-Sc, 2019-01-08 · rulez
Does that Zilog really work on 4MHz? ;-)

I can’t believe it

Great making-of writeup! Got me inspired to create some data-streaming/unpacking algorithm in our Amiga “demo system”. Putting 64 MB RAM in the Amiga 1200 is becoming more common nowadays. Still it feels a bit lame to use that much memory when it could be avoided.

This is simply awesome! Great work!
— Anders, 2020-02-08 · rulez
I’m having real trouble getting this to run on a real CPC 6128 (non-plus). Using flashfloppy v3.16 on a gotek as drive A or B with either the HFE or DSK image all I get is a black screen, the OLED display on the gotek says track 0, side 0. The HFE image of Phortem works OK, except for minor music delays when reading the disk. Batman Forever runs just fine too. I have no expansion hardware other than the gotek plugged into the external FDD port, and all the RAM tests good. Does anyone have any ideas for troubleshooting? I’d really like to get this working on real hw.
— Claw, 2020-08-30

I find most CPC prods hard to watch due to the saturation levels ;) But here I still dig the moment when the clown-pic appears and how the music changes.
