Re: Reverse en + dump of pocket VT-xx based handheld famiclone (Karaoto Video Juego Interactivo)

The unknown author is known as Nice Code Software. "Mario Kart" is a hack of Nintendo's "F-1 Race", while "Metal Slug" and "Crash Bandicoot" are original backports of the respective Game Boy Advance titles.

Re: Curious about MMC5 5209/520A registers

I rewrote the MMC5 emulation for NintendulatorNRS some time ago, and in that test ROM, the ruler does move, but in the wrong direction --- instead of revealing the "A", it lost the "9". :oops:

Re: RAMBO-1 Mapper Investigation

Yes, that is true, I can control how many M2 cycles before ack'ing the IRQ. It is not triggered by the IRQ itself, but since the test stays the same through each loop, I can precisely control which M2 cycle does the ack. I tweak it see it move on the scope to find the right spot. Is not possible th...

Re: RAMBO-1 Mapper Investigation

I successfully converted "Hard Drivin'" to Waixing's Mapper 176. ;)

But yes, for Skull & Crossbones, because it needs both scanline and M2 IRQ counters, VRC4 or VRC6 is probably the best choice.

Re: Curious about MMC5 5209/520A registers

Nintendo's leaked lot check spreadsheets have an interesting unreleased MMC5 game entry: a cartridge conversion of "Famicom Mukashibanashi: Shin Ongashima". It is listed as having used a "HVC-ENROM" circuit board with 256 KiB of PRG-ROM, 8 KiB of PRG-RAM, 8 KiB of CHR-RAM, a battery, and this commen...

Re: RAMBO-1 Mapper Investigation

I don't quite understand how you get to a scanline length of 227 M2 cycles, but it should not matter for the purpose of the test, as long as the PA12 rise and fall is appropriately spaced. I check scanline_count and the number of $8000 reads. If it matches the test case, do this sequence: (...) I se...

Re: Mission: Impossible --> Rescue an rare 42in1 ROM

Show screenshots and/or a gamelist of the 22-in-1 part. If it is the same as the DY-636-42's, then one might just take that one's 1 MiB ROM and replace the 20-in-1 part with yours.

Re: What is MMC5 "3-screen mirroring" good for? Answered inside.

Thank you for the test ROM. I get a picture similar to your FCEUX reference picture in NintendulatorNRS. How is it supposed to look? It's not obvious to me what I should be getting.

Re: Mission: Impossible --> Rescue an rare 42in1 ROM

You still did not dump it correctly; the second 512 KiB half is identical to the first. Once you have correctly dumped both halves, the correct mapper for the reset-based variant will be 233. 226 is for a non-reset-based variant of various sizes up to 2 MiB. I did not understand earlier that the swi...
