1- Which is the maximum prg-rom mem that a mmc3 cart can support?
I dont know if its a rom problem or what cos some games write $fe to $8001 and of course the game doesnt have to much memory.
I mean wich value should i "AND" the $8001 value?
I have been trying with different values and some games work and others doesnt.
2 - Is IRQ generation mandatory? wich games uses it?
3 - Is it ok when ctrl reg $8000 is written to hard wire prg-rom according to bit 6?
3.1 - The bank to hardwire is : (cPrgRomsBanks - 2) * 0x2000; ???
4 - Why command "1" copies to ppu $800 or $1800 2k or mem. doing so will pass in -1- the limit of pt0 and in -2- will write into name tables.
Help Please
