Famicom/NES / 509 in 1 multicart
« Last post by FF_ on March 10, 2024, 11:48:35 AM »
I received this game cartridge today (509in1). I bought it only because of "immortal the" game. When I turned it on, I saw artifacts, although the wiki says that the game works on old CRT TVs.
I checked on my other TV and it works fine.
Problems that it has - JVC c21ze.
No problems - 21DG16KG.
The image is very dark - Philips 42pfl3604
But part of the screen on the Thomson is moving a little, that's why I use jvc.

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."
But after all, some of the Cony Soft games were successfully hacked to MMC3, so it's still possible.
Here's what I learned about the late ports from Cony Soft/Future Media:
"In Crayon Shin-Chan, MMC3 is possible due to the use of CHR banks in PPU $000-7FF and $800-FFF as whole, and in CPU $C000-DFFF banks with garbage and the code is similar at the beginning, so you can only transfer data and change the code. In San Guo Zhi 4 - Chi Bi Feng Yun, at the beginning of the game, CHR banks are also whole, but there are several banks in the CPU $C000-DFFF and they are more complicated, so it's more difficult."

Hey there. I'm not sure if it's too late but the contents of the JG7425's micro SD card have been dumped and released in MAME CHD sets for a while now. Using Google should be enough to find them. Unfortunately the contents are in MAME's CHD format so you can't copy them to the SD card without using CHDMAN to convert it to a regular .img file first. The CHD file is in the "lx_jg7425" folder in the set if you get around to finding it.
