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."

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.

fair point

Very interesting information, thanks for taking the time to write this up and post it!

Here are restorations of some of the "Qi Sheng Long" variants of Nice Code games. These releases never had copyright notices originally; however, a few games in this library originally had two-player modes, which were removed in the currently dumped revisions. Additionally, two games had extended titles: "Indreak" was originally called "Indreak in the Conduit", and "The Worms" was originally called "The Training Camp of Worms". I'm not sure exactly why the titles were simplified, though data for the original logos still exist in the ROM.

In total, I have restored seven of the Qi Sheng Long games: including the aforementioned Indreak in the Conduit and The Training Camp of Worms, alongside Bear vs. Thief, Cool Baby, Doll, Fairy, and Monster Ball. "Bubbles Puzzle" also has a two player variant, though I was unable to restore that one. I used footage of the Japanese "FC Home 88" console as reference.
