Strange multicart
This multicart contains 512 KiB PRG ROM and 512 KiB ROM, but its bankswitching scheme makes no sense to me: PRG CHR 6000=31 Street Blaster V 128 256 6002=32 Three Eyes Boy 128 128 (Mitsume ga Tooru) 6003=33 Boy Soccer II 256 128 (Captain Tsubasa 2) I cannot tell what the chips on the left and right ...

Re: Ling Jie Hu Fa - Shock/ 靈界護法 - Shock (Unl) Crash
Stage 3's PRG bank is corrupt in all dumps, including the one in Waixing's master archive. Supposedly, an early version exists with a different Waixing logo that has a working Stage 3, but nobody has it or can confirm the claim.

Re: Xi Tian Qu Jing II (Unl) Crash Issue
Attached please find my NTSC compatibility patch.

Re: Best emulator approach for the long-run: ROM metadata database? Heuristics? Both?
One way to solve the dilemma would be that in the event of a database-header mismatch, the emulator does not silently correct, but shows a nag window offering the user to adjust the ROM file according to the database.

Re: Dumping educational cartridge (word/excel and other stuff)
The cartridge does not seem to respond to bank register writes at all. It is common that Kazzo-based dumpers cannot dump multicarts or educational computer cartridges because they do not provide correct clock signals to the cartridge.

Re: Dumping educational cartridge (word/excel and other stuff)
Set mirroring to vertical in the NES header, and the graphics will be fine.

Re: Final Fight 3 (mapper 90), get rid of multiplier, issues
There is a later revision of the game on the SC-128 multicart that has a lot more anti-debugging traps that also depend on the hardware multiplier being present, in case you want something to test any present of future ASIC re-implementation with. Older emulators have trouble running it even as an e...

Re: NES Test Market consoles and some deluxe models display colors wrong
It means that suboptimal electrical properties of the circuit board cause a distortion of the video signal which manifests itself in hue shifts ("phase distortion") whose amount depends on the instantaneous signal level ("differential").

Re: NES Test Market consoles and some deluxe models display colors wrong
Seems like an excessive amount of Differential Phase Distortion™.

I am drafting a mapper 446 wiki article right now. It's complicated, so it will take time.

Re: Dumping games from Intellivision X2 console
A question: how generalizable is this method of dumping Plug-and-Play consoles? is this approach suitable for any two-blob device (noac +rom)?
