Arcadia (no, not talking about the Duran Duran spin-off!)

[fmcpma]

Which Arcadia system features are present in WinUAE? What media do its games use? How would (are) these media be emulated? Actually, what are the differences between a stock Amiga (A500?) and this system?

Thanks for any info.

[Toni Wilen]

Arcadia is basically normal A500 + autobooting rom expansion (includes bios and game roms) installed in expansion port.

For supported games check MAME. Games are fully emulated.

Usage is simple, select Arcadia quickstart config and point cartridge rom path to game rom zip (exactly the same as used in MAME)

Default keys:

- F2 = configuration menu
- 1 = start 1 player game
- 2 = start 2 player game
- 5 = insert coin (slot 1)
- 6 = insert coin (slot 2)

You can see some Arcadia games in the Hall Of Light

Where can I get the game roms? Is there a TOSEC set?

Planetemu is down at the moment, so grab some arcadia mame roms here:
Leaderboard as an example.

or Sidewinder

Thanks, found all supported ones at emuasylum. I want to rename the zips and give them a TOSEC-like name. Had a quick look at the winuae source, the file names are hardcoded in arcadia.c. Would it be practicable not to check the file names of the zip files but comparing the names and stored crc32 of the files inside? Or editable outside the exe?

I don't know, but is this the same arcadia.c driver found in mame? It is required to check the files & crc's inside a zip, because sometimes they dumped another revision of a board for a new mame version. Or they made other changes with a romset.

I haven't seen MAME's arcadia.c, only the one from WinUAE and that just seems to compare the hardcoded file names. No CRC checking

static struct arcadiarom roms[]	= {
    { "ar_airh.zip", "scpa211", "airh_", 1, 5, 0, 2, 4, 7, 6, 1, 3 },
...
    { "ar_xeon.zip", "scpa211", "xeon_", 1, 3, 1, 2, 4, 0, 5, 6, 7 },
    { NULL, NULL, NULL }
};


    for (i = 0; roms[i].name; i++) {
	if (!strcmpi (p, roms[i].name)) {
	    rom = &roms[i];
	    break;
	}
    }

Maybe Toni has used the mame names because they are standard. So you can just play them without changing the names.

[thor]

That's why I asked. If the crc32 and name checking of the files inside is not practicable, would it be easier to have something like an ini with parameters like "arcadia.ar_sdwr.zip=SideWinder(1988)(Arcadia).zip"? It's ok as it is now, but a more meaningful name would be nicer.

[Retro-Nerd]

A long internal WinUAE name like for the Kickstart roms would be nice, your're right. There are only a few arcadia games. Maybe Toni could change this in a next WinUAE version, with an autodetect-scanner.

[Toni Wilen]

I did it this way because rom-crc checking system does not really support multiple roms in 2 or more zips (bios in separate zip), Arcadia emulation is really minor part of WinUAE and finally mame rom naming is "standard".

[thor]

Thanks Toni for answering. Maybe one more idea: The bios has to be placed in the rom folder, so it needs crc checking of the bios files only once (or when you rescan them) and you know the name of the bios zip then and you can warn the user if it's missing when he selects the Arcadia (like it's done on the other models). Then when a zip file in the cartridge rom is inserted you check the contents against the prestored crc32's and this way you can handle the bios and the game zip.

[Toni Wilen]

Problem is that there are multiple files in every zip that are all part of bios or game. This can't be handled by current scanner.
