adam image 2.0.0 / PICO-8 / "Unsupported video mode"

[ctshh]

I just installed the lates adam image 2.0.0 on my RG 280V. Runs fine, except the PICO-8 emulator. Trying to start any cartdridge I get, in green letters, the screen

Unsupported video mode
> 160x205, XRGB8888

and it hangs, I have to return by pressing select & start.

Any idea what that might be and if I can change anything to get my beloved PICO-8 running?
Thank you, Christian.

Retroarch PICO8 doesn't work out-of-the-box here either (rg350m). I use alternative PICO8 engines like tac08 and fake08_gcw0 for now.

[ctshh]

Would you happen to have any links for those or a manual on how to integrate?

You have to change your simplemenu config (/media/data/local/home/.simplemenu/section_groups/home computers.ini)

[PICO-8]
execs = /media/data/apps/retroarch_rg350_PICO8.opk,/media/data/apps/tac08.opk,/media/data/apps/fake08_gcw0.opk
romDirs = /media/sdcard/roms/PICO8/
aliasFile = /media/data/local/home/.simplemenu/alias_PICO-8.txt

The first entry in the execs line should be the default, so you might want to change the order.

To be thorough, I'll be a little more explicit about all of the steps:

• Download fake08_gcw0.opk from here
• Put the file here on your SD card: /media/data/apps/fake08_gcw0.opk
• Change the PICO-8 entry your simplemenu config /media/data/local/home/.simplemenu/section_groups/home computers.ini to what is shown below (important: make sure that fake08_gcw0.opk is listed first on the execs line)

[PICO-8]
execs = /media/data/apps/fake08_gcw0.opk,/media/data/apps/retroarch_rg350_PICO8.opk,/media/data/apps/tac08.opk
romDirs = /media/sdcard/roms/PICO8/
aliasFile = /media/data/local/home/.simplemenu/alias_PICO-8.txt

Thank you @Captain-Barge for the solution!

I can either switch to tac08 (using select) or use above solution to make Pico-8 png play.

@eduardofilo any idea if RA PICO-8 should work in your view?

[eduardofilo]

Most of the games I have for PICO-8 work with the RetroArch core installed in Adam 2.0. They are p8 though. I don't know if the png's will give more or less problems. I remember that there were some problems and that's why I kept the standalone emulator tac08.

[Shatur]

It looks like if p8.png extension doesn't work. But if I rename to just .p8 - it works fine.

[a-dekker]

It seems to be as simple as that indeed.

[Shatur]

But this emulator can't run all games. The newly added fake-08 is better, it has better compatibility.

[eduardofilo]

About the problem with PNG's in RA core, see the issue #322 reported by @Shatur.

@eduardofilo , thanks for the excellent work on adam for 280V I just installed v. 2.1

Like the OP, I am trying to run Pico8 using the RA opk, and I get the same issue (Unsupported Video Mode 160x205, XRGB8888)
It loads the game (even p8.png), but freezes with the above display.

I saw there were fixes for the RG350's "Unsupported Video Mode" problems by using Video Scaling/Filters. Is there a fix for this using RA video settings? I've tried with no luck.

Fake-08 and Taco-08 work, but not very well. I have purchased the Pico-08 binaries.

[AIdisneyprincess3000]

@eduardofilo I'm in the same boat as @fuji8bit. For the one game I want to play on my RG280V, I have sound issues with Taco-8 and missing text/color issues with Fake-08. I have purchased Pico-08 and played around but was never able to start a game with the RA opk due to the issue reported by @ctshh. By the way, this is my first foray into retro gaming consoles and I'm grateful for all the work people like you put into these CFWs.

[fuji8bit]

I tried doing the same thing AmberElec does, which is launch the pico-08 executable from the "Tools" menu (would be the "Native Games" menu in Adam.

Long story short, I think I answered my own question --- The RG280V uses a MIPS processor, and the other handhelds that run Pico-08 natively are ARM (RG351V and RGB30). This makes sense since the Raspberry Pi Image is a 64 bit ARM binary (dynamically linked to SDL).

So until Lexaloffle releases more builds (don't hold your breath), or Pico-08 goes open source , Fake-08 is probably the best hope for the 280V, and there's not much to do about it.
