Mesen - Emulator

[BenderScruffy]

I still hope that Genesis core will come this year, all the others Genesis emulator are so outdated now.

try jgenesis as it has a good Genesis core

Mesen won't run after I updated Windows 11, I'm hoping for a fix soon.

Havnt had time to check. However if a certain build lets say windows native isnt running maybe try the .net build?

Will be testing this later as i these days use mesen exclusively for my needs so fingers are crossed

I've had this error in both native build and .net build. Don't know why. Maybe it is caused by Windows.

Ok strange. Got 4 media centers and two laptops in the family all windows 11 all fully updated and all running the latest build fine.


Maybe try deleting the mesen config file? If not in portable mode stored in user folder.

I compiled the native and .NET builds from source (linked to .NET 9.0 because of rolling release) with the default "make" (no extra variables set) and they work just fine for me now? I didn't have to remove the config file, either. I honestly have no idea what upstream dependency update could cause this - the other typical culprits like glibc, libstdc++, and dotnet weren't upgraded on the day it broke...

Edit: There was that one time when a mesa update indirectly broke rendering, I guess? It was upgraded twice in the past 2 days but I doubt that's relevant here.

Very strange. I just tested on my brother's laptop and it's okay. Still don't know what's the problem of my PC.

Did you go into the user appdata folder and delete any old config files?

I've done many ways as much as I can. Still not launch.

Curious


Did you try to dsim and sfc your system

Did you try running as admin?

Also running latest dev build right?

Any way as I can, now the only way is waiting for Sour to fix it. I have to use other emulator this time.

I dont think there is anything wrong with mesen to be honest.

You can try this version—it's one I localized myself. Don't mind the language. Since I added CJK fonts, it wouldn't run after compiling the source code either. So I adjusted the program's stack size to get it working properly.

Is there a way to get the Memory Viewer to display Japanese characters from a .tbl file correctly? I have been loving using Mesen for creating romhacks so far but all Japanese characters display incorrectly as two squares, meaning I have to revert to Windhex for anything with Japanese in it, which is super inconvenient. It would be really nice to be able to use Mesen's on-the-fly ROM editing for Japanese games.

Hello, I've been noticing a weird bug in the unlicensed puzzle game Creatom where the blocks stay stuck in the air when trying to move them to the left. This seems to be the case on other PC emulators, like Bizhawk and NintendulatorNRS, and when loading on an Everdrive, but it doesn't happen on the real cartridge or on Mister. You can see it happening in this short video where the blocks get stuck and a white rotation sprite appears underneath where the block should be: https://www.youtube.com/watch?v=DQHEI-rMlx0

Not sure how reasonable this would be to look into for a mapper used by a few games (Mapper 132), but I wanted to mention this just in case.

When Right key is pressed, register $4105 is checked, but emulators expect $4100, CPU $F3EA (bank 1):

Code: Select all

LDX #$F0
LDA $4015,X ; [$4105]

https://www.nesdev.org/wiki/INES_Mapper_132 "Mask: $E100 read $4100: [xxxx SRRR]", but in Mesen mask is $E103: if((addr & 0x103) == 0x100) { (https://github.com/SourMesen/Mesen2/blo ... 211A.h#L42). I haven't tested it, but I think if((addr & 0x100) == 0x100) { should fix the game.
The game can be fixed by changing F3FB:EB (instead of F0) in the file.
