But why doesn't NES do the same? That's what threw me off. I thought /CIRAM was what got tied to an address line to do mirroring?

"任天堂" has the same meaning to Chinese as it does Japanese, both will think Nintendo.

Original 1987 Namco Famicom mapper

Does anyone have any info on it? As far as I know, no emulator supports it because most people don't know it exists. The dumps for Mappy, Lupin Sansei and others are all hax0red to MMC3.

Famicom's two CHR A10s, what's up?

Why does the Famicom connector have two CHR A10s? Thanks in advance!

I don't have one/them but I can clarify. They're NVRAM cartridges, simply modified licensed carts that can be written to via the Pasofami emulator. The emulator can link to either parallel hardware (not sure if it's sold) or a Famicom attachment for the Chameleon USB, a popular (and now defunct?) US...

They're adapters for the Chameleon USB (a device I've been promoting for years)

I could piece together a better system alltogether that doesn't discriminate against Famicom carts... theres no reason why the NES scene should leave it out, such a thought is ludicrous!

Yeah, I meant it'd be easier than emulating MMC5. And yup, only 1 FDS type. FDS is really close to NROM-256 besides the mapping and extra registers (sound/disk/IRQ.)

One could easily emulate a FDS (before MMC5) but of course it'll require a flexible system due to the FDS's odd mapping. There are quite a few old Taiwanese FDS hardware emulators which are basically RAM adapters which play cartridges and swap sides via a pushbutton.

Don't mean to be rude but this idea has been suggested on just about every message board I've ever visited. I think if someone had the skill and desire, they'd have already thought of this and started on the project already... The problem is that the people who suggest it have no understanding of th...

Do you guys know of the Pasofami emulator? It has support for a DIY interface, the hardware paired with the emulator is capable of dumping nearly any game, with little to no hardware reworking (and this includes Japanese MMCs of course.)

Can you do address decoding for the IRQ vector, $FFFE and $FFFF, shutting the regular ROM off and putting something else in? I think I can, I don't have a good understanding of how fast everything is. I was also sort of wondering if it could possibly be done without IRQs. Somehow if I could simply ...

Guidance please

I'm designing some game enhancing hardware, I have no clue where to begin my hardware's exploit. The hardware will generate an interrupt, which should trigger the console to run some custom code. To do this, I think I need my hardware to hijack the IRQ vector for just that one instruction. How shoul...
