Here you have one.
The latest release of BleuMSX is the first EMU that the colors of "Starship Rendez vous" stage Michelle correct displays on my computer. (in the 2+ mode)
An other
I'm using the same systemroms on all the Emu's I have installed, but OpenMSX won't work with it (I use copy's of roms from my own Philips 8250 2+)
re-edit
To complte the info.
I installed the windows version of OpenMSX.

Well, on one hand the emulator comparison might be biased when I ask emulation developers to report software that causes trouble in Emulators, but it's an undoable job to test every single piece of MSX software available until you have found several titles that are suitable for the tests. Besides, I'm not -only- asking emulator developers, but also the users of MSX emulators to report software that caused trouble on their systems Wink

dvik: Wow, you made a lot of progress on blueMSX.

It's true that accurate timing doesn't have to lead to slow emulation. Most of the time on openMSX is spent on rendering the video output, while audio output can take some time as well if you have a lot of channels (MB Stereo or MoonSound). However, it does take some effort to perform only the necessary synchronisation actions, instead of synchronising the entire VDP every time VRAM is written or a status register is read.

legacy: which hardwareconfig.xml are you using? If you use the Philips_NMS_8250 configuration, you will get a V9938 (MSX2 VDP) instead of a V9958 (MSX2+ VDP). The easiest way to emulate a 8250 upgraded to 2+ is to use the Boosted_MSX2 configuration. If you don't have the FMPAC or MoonSound ROMs, then remove those sections from the XML.
If it still doesn't work, please come to #openmsx on irc.freenode.net or post to the openmsx-user mailinglist (see http://openmsx.sf.net/ ).

Some people seems to believe that openMSX has far better emulation than the other emulators. I can create a quite long list of things where other emulators (NLMSX and blueMSX) are doing a better job with emulation than openMSX

I have two very good test apps that you can add to the test suite:
- the demo Turnix 2
- the game Ark-A-Noah.

Can you please report the problems you have with software on openMSX to us? We would appreciate that very much!!
We already have a bug report for Turnix, but as far as I know, Ark-A-Noah runs fine. Please file a bug report for any other problems you experience in openMSX!

Seems to work just fine on openMSX, at least on the latest CVS version:

openMSX emulates specific MSX machines. So, you should use the ROMs that belong to the machine you're emulating. However, the Boosted MSX2 config of last release is based on the Philips NMS 8250, so you can use the ROMs of that machine for this config. I don't know what machine those 'generic' ROMs are from, but they will most likely work with a machine like the 8250 (although I haven't tested that). You just need to rename them or change the filenames in the config of the 8250.

So, for your case, you should be able to either use your ROMs with the 8250 config, or change the 8250 config so that it matches your real machine better. Then they should really work. But probably they'll just work with a default 8250 config as well, since they also work in other emulators as you mentioned.

Ark-A-Noah runs fine.

The first scan line has some unwanted white dots (running 0.3.4). I found this minor bug yesterday. It seems like you changed the overscan to correct overscan in Unknown Reality. Maybe that broke Ark-A-Noah...

The last few days I found some other problems in openMSX as well (when comparing next blueMSX release with openMSX 0.3.4). I can compile a list and send to you. (I did send one to Wouter already and hopefully it is fixed in 0.4.0) All these findings are minor though.

The only major bugs I found so far in openMSX is a moonsound bug (already reported), mouse emulation in general and the Turnix 2 demo which does not run at all.

Wow, what a woman.
I've tryed countless things, rename,split roms, fresh install, but what I try, nothing works, I'm crying. That woman staying unreachable.
Well, I'll try it again.

dvik: please send a list to openmsx-devel mailinglist.
I don't see any unwanted white dots in openMSX CVS, with pixel acc and Boosted MSX2. AFAIK overscan wasn't changed for UR, but if it was, that was a loooong time ago. More than 1.5 years, I think.

The Moonsound bug should be fixed and Turnix is a bug in Turnix itself, which happens to be no problem on a real MSX and some really minor in-depth low level VDP timing issue in openMSX seems to cause it to crash in openMSX.

legacy: join us on IRC if you can't work it out...

I don't see any unwanted white dots in openMSX CVS,

I have not tried the latest CVS code so hopefully fixed in 0.4.0 Smile

I'll send the bug list to the mailing list. I'll redo my tests tomorrow so I don't send an incorrect report. Btw, do you want me to wait to 0.4.0? Maybe the problems are fixed already.

I looking forward to see the new major release of openMSX !!!!

dvik, if you come to our IRC channel, you can get a current CVS build to test with. Shouldn't be much different from 0.4.0, but maybe we can even fix the problems before 0.4.0 release...! Smile
