Can not find any information about
ExtHiROM And ExtLoROM.
I know only HiRom, LoRom and Ex-Hirom mappers.
What is it?
What games was created with those mappers ?
Thanks

Re: ExtHiROM And ExtLoROM ?
It's supposed to be the same thing. Since "Ex" might mean "Extended" they just clipped it differently. I'd recommend using the more standardized terms.
ExLoROM is the same extension of LoROM (mode $20) in the same way that ExHiROM (mode $25) is an extension of HiROM (mode $21): namely, two ROMs, the first is available in banks $80-$FF and is always 4MB in size, the other is anything up to 3.9MB an is available in banks $00-$7D.
ExLoROM was only used by some ROM hacks, and Nintendo never defined something similar. It's strictly inferior to mode $25 for almost all purposes.

I see better now.

So those names it’s only to extend one big rom file to two eprom’s, is that exact ?lidnariq wrote: ↑Sat Apr 17, 2021 3:22 pm It's supposed to be the same thing. Since "Ex" might mean "Extended" they just clipped it differently. I'd recommend using the more standardized terms.

Thats why I never find any rom file with those kind of mappers.
That’s mean when we using « flash eprom » (with enough of space) , no need to use any special pinout mappers if we have enough of space on flash chip .
Right ?
Re: ExtHiROM And ExtLoROM ?
Mode $25 - the only one that ever had physical releases, as opposed to ROM hackers doing who knows what - always used two ROMs. It was only used by two games - Tales of Phantasia and Daikaijū Monogatari 2 - and they're on the "LJ3x" PCBs.
Other than that the canonical arrangement on disk bakes in the inversion of A23, so you must take the first 4MB and remainder N MB, pad that remainder up to 4MB, and then reverse the two halves.That’s mean when we using « flash eprom » (with enough of space) , no need to use any special pinout mappers if we have enough of space on flash chip .
