tfh, you guys still have the source of that FDD1 vector part? It seems openMSX has a small problem updating the pyramid heights to the SCC volumes...

and the hint for the BASIC part of that disk... Try next TongueLet me check if we still have the sources availbable, but... I have my doubts...

I do not see clear where's the problem with BrMSX. As far as I know, it emulates perfectly ANY MSX1 machine, that is just what I stated before.

So, where is the subset that you are talking about, Guyver? It complies with the MSX standard and it has one of the most perfect CPU emulators. It passes all Z80 tests.

Just out of curiosity: in what respect is BrMSX better than other modern MSX emulators? (Except for the speed.)

The timming, if the timming is wrong, all DEMO will run wrong...

And the "C" key on the command console hung the computer if you not got a joystick.

the SAVE / LOAD don't work for save the MSX2 status....

Don't emulate any european machine.... overall the FDC things....

Don't work with the most of the DISK-ROM only with GRADIENT DISK ROM

Don't recognize some disks formats....

i need to continue?

By the way, great debug console.

I agree with all this, but, AFAIK is the only emulator with separated TMS9918 emulation. All the other emulators do use a V9938 emulation to run in MSX1 mode, and that is wrong.

pitpan, what you say is wrong for blueMSX !

The specific VDP chip for MSX 1 - TMS9918A (NTSC) / TMS9928 (PAL) - is already supported in blueMSX, by disabling in a MSX1 config the specific MSX2 registers of the VDP V9938, what means limitation to only 8 control registers and one status register and only VBLANK interrupt

About the different palette colors of MSX 1, this will be implemented soon.

To be more complete, openMSX make also the difference between MSX1 VDP and MSX2 VDP.

As of now, the debugger. So far only No$MSX and MSKiss have good debuggers aside from BrMSX (I know openMSX had one under development, hope it will be released soon).

imho there's no better emul! all emul have there downside as there upside. To name a few:
f-msx:
possitive - accurate, speed
negative - no moonsound support, not user friendly (imho)

nl-msx:
possitive - user friendly, accurate
negative - relative slow, lacks sound support

ru-msx:
possitive- user friendly, accurate
negative- slow, Midi support does not the sound the same as fm-pack

blue-MSX
possitive - user-friendly, accurate, good sound support
negative - slow (when using smooth scrollers)

open msx
positive - accurate, every msx can be addapted, good sound support
negative - not a nice guy (for openMSX 3.4)

Imho: the best way is still.. Get the original thing Wink

What sound support are you missing? If you have a Moonsound ROM (2MB) and you put it into the 'roms' dir, then you'll even be able to hear OPL4 noise! Unfortunately, it doesn't work well with for example Bombaman, but that's a minor detail. According to Frits Hilderink, a new version of NLMSX will come up soon... Smile

About the differences between TMS9918/9928/9929 and V9938/9958, it is not a matter of disable certain registers, there are some more differences:

-In SCREEN 2, using a V9938 or higher, you can make a VDP trick to use only one bank of tiles. This cannot be done in a real TMS9918.

-TMS9918 supports mixed modes that are not compatible with V9938 and higher.

-Timings are different (YES)

-TMS9918 is not buffered and V9938 is, and they have different bandwiths. I have done some tests, and V9938 supports higher data flow than TMS9918.

Just to make some tests: try to run all the Bandwagon demos in those emulators. If they work fine in the MSX1 mode, then the VDP emulation is wrong. Bandwagon demos only work fine in computers with V9938 built-in. They do use TMS9918 screen modes, but they are not compatible with TMS9918. They originally released all that demos for the SVI-738, a MSX1 computer with a V9938 VDP.

Anyway, I must admit that I haven't tested BlueMSX yet.
