As the title suggests, Animal Land Satsujin Jiken ROM does not work on Carnivore2 on MSX2. I tried every mapper combination by flashing it on Carnivore2 just as trying it on Sofarun. Nothing works, just absolutely nothing. I just get blue screen on ASCII mappers and I get black screen on Konami mappers. Am I missing something here?? The ROM works on PC emulator though. Please help. Many thanks for suggestions

openMSX reports the game as ASCII8 mapper type. SofaRun tries to load it as ASCII16 but forcing ASCII8 does not help. It may be the A.I. patching that is causing issues. I also tried flashing the ROM on a MegaFlashRom SCC+ (no SD) as ASCII8 and then the game boots fine. I don't have a Carnivore2 at this moment so I cannot test on it.

As I said, it doesn't work either. Flashing the ROM with ASCII8 or any ASCII or Konami option doesn't work at all. Maybe it is my machine or something, it is MSX2 Sony HB-F1XDmk2. However I beat a few games on it so far without any issues, so it is probably all fine

I don’t think the issue is with your MSX. The game is definitely ASCII8 so trying any other mapper type is pointless. I suspect the game code has an issue with running in a sub slot. If that is true an RCP file for C2 might be able to make it work (that RCP could make the game run in the unexpanded slot). Another possibility is that someone (gdx is good at this Wink) fixing this issue directly in the ROM, that way the fixed version could also run in SofaRun.

I will confirm with some tests later this morning...

So on my Yamaha CX7M/128 with 8bits4ever SlotExpander and MFR SCC+ with the game flashed in ASCII8. The game runs fine in primary slot but hangs when used in the slot expander. It sometimes hangs directly on a black screen, sometimes I see the "GRAVE MESSAGE" and the image with the fox but the game then hangs during printing of the Japanese text. Sometimes it boots into the black screen, then the MSX resets and I end up in basic.

As a cross checked I ran Gradius 2 with the same config in the slot expander with no issues.

No way, doesn't work at all using any configuration. It's a shame as I look around satsujin jiken titles and I kinda wanted to check it out but there's no way I'm going to, even if it's an extremely simple game... Can anyone figure it out?? Right at this moment I have Carnivore2 flashcart only

The original version (crc32= 15A0F98A) works with the ASCII 8K mapper. There is also another version available modified for the SCC mapper (crc32=AEE2363D). Which version do you have?

HUH oh goodness... Looks like I tried the original version probably as the CRC matched. This one actually did NOT work using any configuration, preferably ASCII8. Once I tried the so called changed version with Konami SCC mapper it... WORKED, at last!! But this is just a mystery the same as murder case in this game why the original version didn't work for me anyway... Thanks for pointing it out regardless. MAYBE it will not crash during gameplay
