I think that's a problem of dimensions... Well, now I could try to "clean" rom from empty spaces but it's a complex task. Your card it's reflashable without CH341A?
Hi, I have the same task to solve for my MXMs. For test I swapped VRAM data from 4150 to 4130. Now the rom is larger (64k) but I think that will be ok.
Let me know.
