Famicom/NES dumps / Re: Looking for Star Keeper ROM dump
« on: March 14, 2024, 08:29:39 AM »
Also, I have taken a look at the Steam version's StarKeeper.exe. While it does have NES 2bpp graphics, there seems to be no 6502 code in there, either.

Attached is the only ROM chip data of the cartridge of Star Keeper. As far as I see it, all it does is play sound and send controller input to the CPLD.

No, because the game itself runs on the CPLD. The 6502 program only reads the controller and plays sound. It's basically like the DOOM cartridge except that you don't see it.

I don't know that these games were "hacked"; I think Cony at some point recompiled the games themselves one they obtained access to an MMC3 clone that was more affordable than their own custom mapper.

In any case, VRC4 may be an easier target for hacking than MMC3.

No, and creating one would be difficult, as the game uses 8x16 sprites, which make the MMC3's scanline counter act near-inscrutably: "When using 8x16 sprites, PPU A12 must be explicitly tracked. The exact time and number of times the counter is clocked will depend on the specific set of sprites present on every scanline. Specific combinations of sprites could cause the counter to decrement up to four times, or the IRQ to be delayed or early by some multiple of 8 pixels."

The game already runs as mapper 4 submapper 4. I made a small change to the IRQ code to run it as regular MMC3. I only checked the initial screens, however.

Famicom/NES / VT03 Octopus CHR problem correction
« on: January 01, 2024, 04:12:53 PM »
A correction for the quit screen CHR problem earlier versions of VT03 Octopus.

The CHR data contains letters for POWER JOY LTD, but the name table data uses empty tiles for something else already.

A later version, found on the "Sports Game 69-in-1" PnP, corrected the problem by replacing the animated faces with boring "Yes" and "No" letters.

Famicom/NES / Pikachu 5 NTSC status bar position change
« on: January 01, 2024, 04:09:24 PM »
Pikachu 5 must have been written for Dendy PAL consoles, because the character portraits are cut off by overscan on NTSC CRT television sets. I modified the game to move up the status bar by eight pixels to compensate for that.

Yeah, I cannot make much of anything of the DGUN-2572 dump.

Any remaining corrections will have to wait until the next update, whenever that will be. (I hope it will be when the Hi-Res versions of the Cube Tech hacks are dumped! :) )

Those size corrections are a bit too much to look at and add for the next version to be released around New Year's Eve/Day, but I will consider them for a future version, if that is okay with you.

On which PnP or multicart did the "Conte" hack of Hokuto no Ken appear?

Edit: given this ridiculous ASCII message at the beginning of the ROM file, I am 95% certain that this is fake and should be removed:

There are three execution environments on the Doctor PC Jr.:
  • BIOS only: run a "custom-headered NES ROM" from a floppy disk.
  • SM-DOS: boot the SM-DOS system disk and run software from DOS-like files.
  • MCC-DOS: boot the SM-DOS system disk, then run a Terminate-and-stay-resident program that loads the 256 KiB Hanzi font into CHR RAM from the system disk.
Each piece of software runs in one of the three environments. TTOK runs as BIOS-only, as do pirated commercial NES games. Most Chinese software runs under MCC-DOS, while the BASIC interpreter only needs SM-DOS.

Recently, I did a large study on "educational computer" Famiclones. As part of this research, I ripped many ROMs from various educational computer systems and cartridges.
(...)
"xue si dian nao (dr. pc jr., unknown input).nes" needs the PS/2 keyboard that the Doctor PC Junior takes. If you want to run it in its native environment, place the attached DRPCJR.BIN into the BIOS subfolder of your NintendulatorNRS folder. Run any normal NROM game, like Super Mario Bros., in NintendulatorNRS, then select Game->Machine Type->Bung->Doctor PC Jr. (*) At the Doctor PC Junior boot screen, insert the attached GAMES.IMA 1.44M disk image via "File->Load 3.5" disk...". Select file TTOK for the typing tutor. Set Scroll Lock so that all keyboard keys register instead of being interpreted as emulator control keys. You will also find the native form of the FC7005 "cartridge".

(*) This treatment as a "plug-through device" may seem awkward but is technically correct, since the Doctor PC Jr. has a cartridge slot, and its BIOS sits between the cartridge slot and the CPU. It only seems awkward because while NintendulatorNRS must have something in its "cartridge slot", a real Doctor PC Jr. will run its BIOS with an empty cartridge slot.

So I finally managed to fix the music in Balloon Shoot. The note table that translates note numbers to frequency values starts at F900, but the first five bytes had been replaced by tilemap data for clearing the START line. I relocated that tilemap data to EFF0 and corrected the start of the note table. This indicates to me that the original (CHR RAM having) version, wherever it may be found, had no or different music.
