hey guys! since i already posted a trhead long ago trying to make some rockman 2 hacks to work on a normal console, i got a spare of Faxanadu and Megaman 2, and they have the same layout
Megaman 2:
Faxanadu:
i patched rockman 2 with the hack im going to use and it went to 267 kilobytes, i splitted the chr and pgr and this rom has no chr, but it had 11 kb char cuz of the hack maybe? and 256 kylobytes from the pgr, so since megaman only uses pgr beeing mmc1, does the hack rom make it use chr rom? btw im new to the chips and those stuff, i dunno iwch ones to choose, and dunno how to identify, but someone already told me, that i need a 2 megabits chip for the cartridge, so what i searched for 2 megabits 32 pins eprom ( since i think those are the ones i need to use) and i found some options,
i found an:
AMD AM27C040-90DC EPROM DIP-32PIN IC 27C040
an
AM28F020-200PC AMD 32-PIN 2MB FLASH EPROM NOS AM28F020
and a
AE29F2008-12 ASD 2M EPROM EEPROM Flash Memory W29C020C-120 29C020 IC
i also found some cheaps 27C020-15 27C020 Memory UV EPROM
this one are the cheapest i found so far, would this one works whitout resoldering, since this ones are 32 pins, same as the megaman 2 and faxanadu cardtridges?
those three are 32 pins and 2 megabits i think so, and i was wondering, are they any cheaper? or even some cheaps, or maybe other models cheaper to use, because i didnt know they were like 8-15 us each one, so anyone mind giving me a help here, i really need to start working on it.
Btw, im worried about the rom hack since it made a chr rom of 8.5kb, do i need a eprom for it? or no, the pgr is 256, any help here please?
remember, you are talking to a totaly new guy, who dosnt know about chip prices, models and stuff.
i would also like to know if i could use the faxanadu copy to make the megaman 2 hack works.
if i use the last chips i wrote, what do i need to bend and sold with what, an iamge would be better if its not to much ._., like what to where and that stuff, im so new and im frustrated atm C:
thank you in advance ( btw sorry for my sucky english )
