So,
I've been trying to burn 2x 27c040 EPROM to be used on a Mega Drive cartridge according to
this page you are supposed to connect A0-A18 together to mask ROM
D0-D7 from 1st EPROM to D8-D15 on mask ROM
D0-D7 from 2nd EPROM to D0-D7 on mask ROM
CE and OE together to mask ROM
I've left Pin 1 floating and connecting it to 5V/BYTE won't make a difference.
However, it simply won't work.
I'm trying to burn the game Uwol Quest, which is a homebrew game. I've also byte swapped the file. No success. Am I doing something wrong? Does this 8Bit to 16Bit thing even work?
Help appreciated.
