Has anybody of you guys tried those Konami MSX Antiques series on playstation?
I have all them. To me, those games seem to be exactly same as on msx.
I wonder if there's emulator running those games?
If it is an emulator, maybe it could also run other .roms?

Maybe you gurus could check them...

afaik it's an emulator, but it's not totally accurate; pretty close though.

I don't think it would be legally allowed to run other games using that software (even if it's possible)

If it's an msx emulator in the background, is it based on the fMSX sourcecode? Did they pay the MSX association for using MSX-roms? Or did they recode the lot to work without roms. That would be nice to check, if someone can check the content of the cd-rom for (cloacked) roms, or disassemble some psx code.

I found this emus4psx.host.sk/ekonami.htm while googling...

Was there an MSX Association in 1998? Wink

For what I know (after some investigation), Konami changed the game roms to run without the required BIOS ROM by recoding those routines. Texts have been changed to be correct for the Playstation and adapted menu control where necessary. It does run in an MSX emulator. Which one, or on which one it's based, I don't know.

Indeed, Konami didn't use a lot of BIOS routines. Only setup (like INIGRP and similar) and for keyboard/joystick detection. Anyway, I have little experience disassembling Konami games.

I guess that they coded their own emulator, or instead, improved some fMSX. There is a PSX version, but I have never tried it myself. It was a bit slow, wasn't it?

AFAIK Konami set up the VDP registers themselves and never used the INIGRP call to do that.

I only know the PSX version Konami put on the collection discs and I haven't experienced any real difference in speed.

You overestimate emulation potenrial. Something like fMSX would run at ~2-3 frames per second on Playstation. Ever heard of static recompilation?

bullcrap!
Ofcourse it's emulation! The rom images are even on the CD!

PSX has a 33MHz R3000 CPU, that's more than enough to emulate an MSX1.
