Question about XBLA Arcade Emulation

[beamish]

Progress! (somewhat)

 

So after extensive research, I was able to track down a BMS script capable to extracting the simpsons.sr file

leaving again 6 files, this time with .KON / .ROM file extensions.

 

Again, these files showed up in MAME, but after trying to load the game, i'm met with this message:

 

 

 

Here are the files with MD5/Checksum:

 

Simpsons_4J.KON - aea60dcc4c372310a33be37474ea80a5

Simpsons_4WA.KON - 9184fa8dc11dcacfbbd0ff043bc2388f

Simpsons_SAMPLES.ROM - f035fa135c057375931c5d05fed11a04

Simpsons_SOUND.ROM - 8f668a0ad3943644efd66addd9dbda50

Simpsons_SPRITES.ROM - 32de9f1d89cd53410d4bae775ffe8369

Simpsons_TILES.ROM - 9b9c7e7c97143d300c3a6a981e6a7e89

One step closer, I can feel it!

Hi there, took a bit longer than expected..

 

If you type at the command line:

 

mame simpsons -lr

 

you get:

The default menu simply checks if the zip file simpsons.zip exists but it doesn't see what's inside. When you attempt to start the game, then it does the in-depth check, and fails. Mame doesn't actually care about the filenames of each rom, it only requires that the CRC matches. However you are missing a number of files, so it doesn't run.

 

Typically, all the graphics roms used in mame will be merged to one for the ports on other platforms, same with the program roms, etc. That's why you only get 6 from your roms.

 

Hope this helps! If you want it to work on mame just find and download the romset, there's heaps of places. Just google simpsons.zip rom and you get a whole page of sites.

No problem, thanks for the detailed answer!

 

Thats what I was afraid of. I was hoping to go the legit route and play a dump of what I purchased.

 

So these files could technically contain a playable game, however they have been packaged for specific ports, therefore making them unreadable?

 

Many thanks again!
