Hi all,

I'm hoping I am posting in the right section. I've tried Googling this however can find no results.

First of all, I love MEKA. Only discovered it last night (I have been using Dega for years, however I've recently accquired a PC gamepad and needed an emulator with which I could configure the buttons).

On Bubble Bobble (EU).sms ROM I can get to Level 11 however it will then "lock up" and not go past that stage. It is the whole game that locks up (sound as well as gameplay). I can exit fullscreen of MEKA and re-load a ROM, etc.

I have been thrashing my Sega ROMS since getting this last night and no other games have issues. Any idea of a fix? Thanks in advance.

OK, one thing to note is that MEKA isn't a very accurate SMS emulator (sorry Bock) - the Z80 core is balls-accurate, but the VDP has plenty of things that can be fixed easily (assuming it's not as messy as libmodplug), and should.

Are you sure the ROM is good? There are tools out there which can check the "TMR SEGA" checksum.

With that said, turn on the MEKA debugger, and try to pin down roughly where it crashes. A save state would be good, too.

I recall the same bug has been reported years ago, I assumed it was fixed but apparently not. If you have a savestate of the level before the crash it would be helpful.

Out of curiosity are you running in PAL/SECAM emulation mode, not NTSC?

As mentionned indeed MEKA is not the most accurate emulator nowadays, but I'll do my best to fix it whenever possible.

Thanks for the replies.

I was running it in PAL/SECAM emulation mode, not NTSC. I will get a savestate of the level just before the crash for you.

Do I upload the file to here? I am not overly sure sorry.

I do not have any experience with working with debuggers so I do not think I would be able to pinpoint the problem myself.

Thanks again.

If you ZIP the savestat you can add it to any message here as attachment. Thanks for your help!
