I barely understand what you said about mirroring but thanks for your interested in my tpoic anyway heheh
Basically I'm so desperate to do this that I even built 12MB dev-cart today. Basically it is designed for 8MB memory (exHIROM) + 4MB memory configured as LOROM. All memories have been connected exactly this way:
74LS139 is connected like this:
02-MAD-1 pin#12 (shared with PCB)
04-/OE ROM 4MB (LOROM)
05-/OE ROM 8MB (EXHIROM)
(and pin#16 is +5V)
I can confirm once again that Star Ocean configured this way does NOT work on this board: 8MB ROM consists of ROM2+ROM1 (written in this order) and 4MB ROM is ROM3.
Anyway I also programmed Holy Striker Batman 12MB ROM (provided by tepples) the same way as Star Ocean above. Here's what I got:
Is this correct??
