Not using a VRC chip is the easiest solution.aodinets wrote:viewtopic.php?f=9&t=3480&start=75#p120092

Unfortunately anything you write on the ROM region will end writting to VRC registers. Gimmick! uses a area which on FME7 and Sunsoft 5a are empty so no conflicts happen.
And anyway Suikan Pipe is a horrible hack because it has bad music anyway (VRC can't bank the DPCM region so you get bad DPCM sound).
Find a FME7, 5a or even 5b cart without sound (Some Gremilins catridges had 5b inside without using the sound part) cart to make your Gimmick! cartridge.

If you want to use VRC4b mode to run Gradius II RPG, you must use a chip with A17. A17-VRC4 chip's 29 PIN can work properly. I tested it!
