@mitu How would I go about establishing that?

Do they have a license file accompanying them, or the emulator includes a Readme/License file that explains the licencing (re-distribution/modification/etc.) ?

For instance, the source release of M88 that I found specifically says that ROMs are not included and user must get the ROMs from the machine (https://github.com/rururutan/m88/blob/master/README.md).

Zering

@mitu Ah, that's my bad. I didn't pick them up from the emulator's websites, so my guess is the .zips I found were edited.

Thanks for clarifying that.

@Folly Interesting! I might try that. Not sure my computer will be thanking you for the extra work though ^^

I'm still getting sloppy results in lr-quasi88, even after installing from source. I see the extra CPU option in the RetroArch menu but it doesn't seem to do anything.
Could you point me to the directory where you found the file that you edited to set the value for that option to 2?

Press F1 -> option -> sub-cpu -> alway ........ -> F1
(restart)
or
q88_sub_cpu_mode = "2"
in
/opt/retropie/configs/all/retroarch-core-options.cfg

@AdamBeGood Don't worry about it matching. Get the BIOS straight from Project Neko. If it still doesn't work with those, we know the problem is coming from something else.

I've installed Project Neko on my PC (well, downloaded that is, installing is a stretch), and there don't seem to be BIOS with that, or on the site. I'll try googling around.

Edit: I feel like I am jinxed, or like I'm being a real idiot today. There is some kind of BIOS included as games are getting further than on my Pi (while still not loading).

Zering

@AdamBeGood You're jinxed ^^

I think I'm having some bad luck myself, with PC88.

@Folly Still no luck with PC88. I've reinstalled from source twice. The sub CPU setting is set to the right value.

But, testing with Final Crisis, my video output looks nothing like yours. There are basically no colours besides white and purple, yours has a bunch of red and other colours.

Perhaps you have an older verion of the game. The older versions of the pc-88 just have a few colors.
Is you version set to V2 ?

My game version has 5 disks.

Zering

@Folly Mine only has three.

What is your rom named?

@Folly I mean Final Crisis ^^

@Folly That's the exact same version I've got.
Could the differences be because you're running them via .m3u?

Don't think so, you can try though.

Then you have to add .m3u , as sudo user, in :
/etc/emulationstation/es_systems.cfg

Zering

@Folly You were right, it made no difference.
Do you have any idea what could cause this? A faulty BIOS maybe?

do you want my sums ?

Zering

@Folly Sure, it can't hurt!
Thanks for all your help.

Before I updated from source I also changed a few to make them the same as in the docs.

Will hear your succes later on.

Zering

@Folly When you say 'changed a few', do you mean that you've replaced the file entirely or that you've somehow edited the md5?

Edit : Got it! My N88.ROM was way off.
As a note, n88jisho.rom is still wrong on my end. But Final Crisis plays fine. That file seems to be optional.

Thanks again @Folly !

I've got a load of games to run tonight, with quite a bit of disk swapping. So the bios I have is good for something.

Do you think I should raise a post for my .hdi issue?

I could do without all the drive swapping, and I have to use Google Translate on my phone to find out what the game wants me to do!

Games I've got to run -

Dragon Slayer 2
Puyo Puyo
Popful Mail
Rusty
Warau Salesman (not recommended, this was when I was picking any game to try)

Only one I've had no joy with is Night Slave but that has Disks A to J so maybe needs to be installed? I think that might have to be run on .hdi (it looks quite fun so wonder if you guys want to try it?).

Zering

@AdamBeGood So there's only one game you can't get to run?

@Folly That's excellent news!

Makes me wonder if CD and HD images can also be added together with FD images. All together in 1 file.

You can mount different types of images together using one cmd file (a little like a m3u file. Read here.
