Here's a patch by request for DDP2 to force Korea region.
Apply to 'v102.u8' from MAME 'ddp2.zip' and burn to an M27C160 EPROM.
Let me know how it works for you @yonggarri and anyone else that may find it helpful - cheers!
As always xdelta UI can be found here: https://www.romhacking.net/utilities/598/
In Japanese version you start with 3 bombs and in this version you start with 5.What's the deal with changing DDP2 from JPY to Korea other than the language change? Modified difficulty?
(Apologies if mentioned above already.. I looked up but couldn't see any answer in a handful of pages!)
@GC8TECH sells high quality reproduction carts of the three Cave shooters that include the proper 5V circuitry.Are there guys on here that sell the converted PGM carts? I've got Ketsui but would love to add Espgaluda and DDPDOJ. Also is DDPII available as a conversion?
