Also a additional note about the pre-releases/beta versions of AC3.

Krishty hat geschrieben:Thank you for the clarification! One more problem in finding leaks: Even if Namco or some employee stored pre-release AC3 data on CDs, they are likely to rot after 20 and more years. Hard drives start to demagnetize after such a long time. The arcade leaks RythusOmega mentioned have often been found on floppy disks and I doubt anyone used them for long-time storage in 1999.

reading Krishty last post made me remind of a story i have seen long time ago. which Namco unfortunately have lost all the AC3 files from their hard drives, i remember that in 2007/8/9 i was looking into internet, then i have found a post on twitter which a fan has asked to a namco dev about if a AC3 remake was possible, and his reply was it´s was not possible due by their lost all the data about it. the source about this i can´t find it anymore because that´s was very long time ago and for founding it´s gonna been a hard task along that i don´t know if is true or not. but one of the almost "proofs" that they lost AC3 data was on the Famitsu interview of the Update 2.07 of Ace Combat Infinity, which when they asked Kono and the Devs about of R-101, one of the Devs in the interview said that other dev of the team needed to brought his PS1 and his AC3 copy to using as a reference for the recreation.

Famitsu: I see. What was the most difficult update so far, dev-wise?

河野 デルフィナス(R-101 Delphinus。『エースコンバット3 エレクトロスフィア』が元ネタの架空機体)を導入するとき、HUD表示を原作風に作り直し始めたのを見て、「本当に大丈夫?」ってなりました。『インフィニティ』と『3』では仕組みが違うため、スケジュール通りに仕上げることが難しいだろうと。シリーズのファンに喜んでいただけるならと、現場を信用して任せましたが。

Kono: When we put the Delphinus (R-101 Delphinus from Ace Combat 3: Electrosphere is an original fictional aircraft) in, we wanted to recreate the HUD from the game it originated from. When work on it started, we all felt “Would this be alright?” Because the makeup of Infinity and 3 is quite different, it was really difficult to get it finished on schedule. We wanted the fans to be able to fly it, and so we had faith in the dev team.

小柳 デルフィナスのHUDは、プログラマーが自宅からPS oneを持ってきて、『3』のゲーム画面を見ながら作成していたんですよ。

Koyanagi: The dev responsible for the Delphinus’ HUD actually brought a PS One and played Ace Combat 3, and made the HUD while looking at the game.

I read the interview differently – the dev looked at AC3, but he wasn’t forced to.
  1. HUDs move, switch modes, and have many symbols. You cannot re-create them from looking at their source textures, you really need to observe them in action to understand them.
  2. Actually, a few paragraphs later, they state that the developer started re-creating the R-101 without help from management:
    We were looking at production estimate costs when the dev already went ahead and making it. […] That particular dev was such a huge Ace Combat fanboy he really couldn’t be restrained (laugh).

However, I believe you when you say a staff member tweeted that the data is lost. I have an authorization from a major video game publisher here to write a patch for one of their abandoned games but work never started because they cannot find the source code any more. „Ask developer XYZ, maybe he knows someone who has a copy of the code.“

RythusOmega asked me for help regarding Ace Combat 5’s ULZ files. Specifically, he needed an ULZ unpacker.

I quickly wrote one:
unpack_ULZ <in file> <out file>
(4 KiB) 9-mal heruntergeladen

Here’s a recap on what I did:

  1. I downloaded Arthur Richard’s acanalysis (the entire bin folder).

  2. Sadly it doesn’t run well (hangs/crashes). I tried to build it myself, but it doesn’t compile well and I had no time fixing it. So I applied some compatibility settings to AC4Analysis.exe and retried a few times until it finally worked.

  3. I opened DATA.TBL from the Ace Combat 5 disk:

  4. I double-clicked the first data entry “00000000” (single-clicking doesn’t work) and exported the file:

    step3.png (3.28 KiB) 124-mal betrachtet

  5. These files are clearly ULZ-compressed:
    step4.png (9.28 KiB) 124-mal betrachtet

  6. After running unpack_ULZ 00000000 00000000.xtracted, I got a cleanly decompressed archive which starts with text in Japanese Shift-JIS encoding:

I suspect the archive format is similar to AC2’s or AC3’s, but someone else has to figure that out … my weekend is over :(
