What's new

Metro VG420 Multi interest and development thread?

Got this all built & soldered and I gotta say, this multi & games kicks the crap out of mah-jong.
But you can still play all 3 versions of mah-jong if you want. Personally the cherry/fruit version looks interesting.
Thanks @twistedsymphony for making this possible!

I made Japanese versions of Lady Killer and Karate Tournament.
Karate Tournament worked just fine by applying existing patches to the Japanese ROM.
Lady Killer has different addresses, so I created a new patch based on the original one.
I wish the Japanese version of Lady Killer had a sexy mode.

Sir , witch ones are the existing patches ? Are the ones provided by the TS's tool when you compile the roms for the multi , because i checked the mame zip and there is the JP version of the game with 3 files . is only 10g , 8g , 1d from JP needed to be replaced in the main folder ?

For Lady to be GONTA i understood how to be done . Big thanks !

I also installed — mine still in testings 👍🏻

That was a poor explanation on my part.
The file is replaced with the Japanese version,
So those are the three.
Karate has no problem applying the patch for the foreign version to the Japanese version rom.
For Ladykiller, you can apply the patch I made to the Japanese roms.
I didn't attach the bat file I made for synthesis because I wrote it at random and it depends on my environment. Sorry.
