NOT WORKING machine

Rock Fever 1 (IGS)

I think this is more than just "/* need internal rom of IGS027A */" as there don't seem to be any dumps listed, not even NO DUMPs of anything other than the program ROMs.

apparently this is some kind of custom board + PC combo in a dedicated cabinet.

the lack of any kind of documentation of what this is isn't really acceptable as-is IMHO. It isn't even clear if it should be using regular PGM BIOS ROMS for text etc. or if those weren't present either.

Most assets are missing right now as I haven't got time to make an adapter that plugs in the ROM board to dump each chip. Will do that and archive them once it's been properly dumped.

they should be listed as NO_DUMP at least. Likewise needs comment about it using PC hardware for the video etc. too (which will also need dumping at some point)

Will make some changes to the code and document the board later. The architecture is very similar to PGM as it uses 68K for the main program and has the IGS027 for other purposes (DRM or sound? not sure yet.).

actually I don't know if there was a PC side at all, there seems to be conflicting information on this, so yes please provide full information so we know what it is at least!

we need to know if it uses the same video and sound chips as PGM too, which are as important as 68k and 027A for deciding if it belongs in this driver.

The very first Rock Fever uses 68K for main program, IGS023 for video processing, and an IGS027, probably for copy protection or sound processing. Subsequent releases, Rock Fever EX, 3, 3 Plus and 3.5 MAX, share the same PCB, where two IGS027s are used, the graphics system remains unchanged (IGS023). Rock Fever 4 and 5 are PC-based games. They used IGS027 for handling IO, and later models the 027 was replaced with IGS036.

Information about this series is sparse, but I will create a diagram for documenting the board and add it to the file.

My friend has Rock fever 3 plus to dump soon, there is NO PC , it's a pgm-like mainboard with all the content on several "rom cards / simms" similar to the CPS3.

If a way to dump the "carts" quickly is made, please contact me about it... Cheers!

NO_DUMP lines don't need to be commented out; it won't list the NO_DUMPs when MAME starts, or in MAME's XML output if they're commented out

More letters for the shortname please? Like rfever. rf, yeah it's not taken yet, but not descriptive at all. And if everyone did it, we'd run out quick ;)

happppp avatar Jul 24 '24 17:07 happppp

also rf2 is taken, which would cause problems later when adding rock fever 2

This may probably be redone from scratch rather than dealing with conflicts.
