All MegaROMs have a mapper mechanism that would have to be implemented with extra circuitry.
OK manuel thanks,then to non MegaROM like ZANAC no have problem?though I imagine that does not work on a mapping konami,non megarom konami mapper?or just i need ascII mapper,thanks you.

no problem with simple 16k or 32K games (konamis or not).

and you needs to burn the .ROM version, because .BIN has the BLOAD's header and extra loader code.

hi where can i find some schemas to convert a mega rom konami to a working eprom 27c020 in it.

reprogramming it is not really needed, but can be nice.

thank you.

27c256 = 32k
parodius and salamander = 128k
and the original mask rom have not the same pinout with an eprom
this is the bad way

But your Konami mapper that uses Eproms 128K,256K,... have there address and datalines 1 on 1. So no swapping of the pinout like on the original rom?

the problem in this post is not the swapping data but the original konami mask rom have 28 pins and the Eprom 27c010 32 pins
