MAMEWorld Forums - EmuChat - Adding drivers for Dotemu's IREM roms/compiling help.

I recently bought a bundle of IREM arcade games from Dotemu and, partially for my own edification and partially because the included emulator has a lot of issues on my laptop, I'm interested in adding drivers for these to MAME (for my personal use, if nothing else).

I've been looking at R-Type Leo first.

1. I'm having some issues getting the MAME 1.5.2 source to compile. At the linking stage, I'm getting an error about an undefined reference to driver_xorworld in drivlist.o. Commenting out the two lines referring to xorworld in drivlist.c lets me finish linking, but is doing this going to cause other problems?

I'm also getting this access violation when launching the new executable. The official binaries work fine, it's only the one I'm compiling myself:

Code:

2. The standard MAME rom archive and the one Dotemu has are structured differently, although that actual data appears to be pretty similar. In the Dotemu ones, most of the individuals binaries have been merged. For the most part, I've found which MAME binaries correspond to which Dotemu binaries, except for one.

The MAME rom archive has a file called rtl-da.bin in the R-Type Leo romset, and m92.c has this getting loaded into a ROM region called "irem". The other games in the m92.c driver source do something similar.

Any idea what this is for?

Thanks!
