Dump 64 in 1 Bootleg Cartbdrige Problem

[Blunern]

Hi OSCR team. I recently bought a CR V5 Dumper cause I want to dump a bootleg Famicom cartridge named "64 in 1" from Dynavision", but I don't know how to use it to achieve that. I have tried with some mappers and nothing useful. Could you help me or guide me, please?

Hi, try mapper 226 with PRG=1024 or 2048

Sadly same condition in emulators with Mapper 45, its strange and sad :c (Sorry for my bad english)

well you need the dump to be good before trying to play it in an emulator

Hi, I was half successful in dumping a similar Dynavision cartridge with the same name(64 Games), but with different music and list of games. The menu was dumped but the games don't work. The mapper is indeed 226 and PRG can be either 1024 or 2048, it doesn't matter.

I'm actually looking for help, I want to get the whole cartridge dumped with the games working but I don't know how.

Same issue with these. I can't figure out how to dump them. Any ideas.

They look like BlazePro carts so most likely mapper 468 and 128MiB PRG-ROM.
Such a big ROM size is not supported by the current OSCR code and need a custom script to be dumped.
