Hi!
I've been playing around with some of my VRC2 and VRC4 boards and I wanted to try to replace the VRC2 chip witch a VRC4 chip on a Jarinko Chie cart.
I burned a set of Kid Dracula translated roms and I rewired the PRG ROM as an UNROM EPROM conversion and the CHR ROM has been unmodified as it's a 32-pin socket. (I've also made a Getsu Fuuma Den repro using this board and I didn't need to rewire the CHR rom at all, it just worked).
I then followed the VRC-pinout to be sure to use the correct setup for VRC4e submapper and the game works....but not all is working. The status section at the bottom is totally corrupted and some of the background graphics are also corrupted.
Is it not possible to convert a VRC2 board to a VRC4 board?
Has anyone tried this before?
Thanks
