Not sure if this could help on implementing HuC3 (this game probably has little documentation), but 'Robot Ponkottsu 64 - 7tsu no Umi no Caramel (Japan)' is an N64 title which used the transferpak to receive data from the japanese Robopon GBC titles, Sun/Star/Moon. (These games have custom cartridges with speakers + a replaceable cr2025 compartment, and use HuC3.)https://github.com/Drenn1/GameYob/issues/51#issuecomment-16026325Phenomenal work so far by the by, very impressed at the support for custom carts like pokemon rumble pinball and the gameboy camera
Latest version of 0.63 fixes the screen problems thank you! One last request, and this may be too much work / too difficult, so it is fine if say no, please don't worry about it! Can you figure out how to dump saved games from Mega Memory Card by InterAct? I've got a few carts with dead batteries so I can't restore saves from MMC in order to dump them with ed64. I guess I can figure out how to change the cart battery evenutally tho..I dumped MMC rom and I can see the save game file table at 0x7800 with my save file titles listed and if I run the DEMO.GB rom in an emulator it show my games in the delete menu like normal. So if we're lucky getting at the saves might be as simple as overdumping DEMO.GB?Anyway I'm very happy with this program as is already thanks so much!!! edit:Here is a picture of MMC.Also it seems all of 0x7000 ~ 0x7FFF is used for file management. I see this by comparing with never used MMC rom file from the net.0x7000 ~0x7800 looks like a FAT table!
I got it to work and was able to repeat it one or two more times. I have everdrive64 v2. Here are the steps I took:1. System was turned off2. Plugged both gb camera and transfer pack SNUGGLY into the controller on port 1.3. Turn on and start libgbpak beta v.6 (with sram write)4. Libgbpak makes the gb ding sound and shows the "check connection" message on the bottom and NO -1 or -45. If requirements in step 4 has been met, then slightly pull the gb camera out JUST A LITTLE BIT instead of it being all the way in the transfer pack. I am talking about 1 or 2 mm.6. Press the reset button on the system - not powering it off.7. Start libgbpak again with a little prayer...8. Once it shows the name of the game, press B to dump the SRAM, and be patient because it is about 128KB.
thanks for that link, this might come in userful.it seems like there are a lot of abscure mappers supported by this emulator like:mbc7tama5huc3ROCKMAN8BCMMM01POKE8IN1MK12
I built a standalone GB cart reader with support for all of the official mappers.I dump HuC1(0xFF) as MBC1 and HuC3(0xFE) as MBC5.MBC7(0x22) and TAMA5(0xFD) are the problem carts when it comes to save games. MBC7 uses reads/writes to 0xA080(Kirby)/0xA180(CMaster) and TAMA5 uses 0xA000/0xA001 for both ROM and RAM.
