Just a guess ;-) Well, there are plenty of sites with the ROMs on the net, it's rather pointless to take a lot of trouble to rip them from the Antiques CDs. It could also be to make it harder to replace the ROMs with other MSX games and create your own Antiques collection. However, encryption would have done a better job than compression, especially this compression format which isn't too hard to reverse engineer. Really strange to compress the files, when a dummy block of app. 16MB can be found on the CD. This has no meaning :-(. For some reason the PSX can't read the final part of a session. Therefore all games should have dummy data at the end of their session. Bye, Maarten -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html

Konami MSX Antiques - Emulator
Hello, Some people already notices that the files on the Konami MSX Antiques for the Playstation are more or less the standard MSX ROM Images of these games. This means that there is at least some mlevel of emulation. Can anyone "dive" into this? Maybe this emulator can be used to play other .ROM images as well. This way we can play lot's more MSX Games on our PSX... Regards, Arnaud --Go visit the MEP:MAIN: http://www.file-hunter.com/FAQ: http://www.faq.msxnet.org/
Re: Konami MSX Antiques - Emulator
Hi, According to the info I got, the roms on the cd´s should be modified in the way that they don´t use any BIOScalls... So in that case well, you can forget about using it for emulation thus there is no bios incorporated in this emulator... Whatz up with the GFX9000 version (normal screen) of eggbert and moonsound muzic?

Hi, Interesting... Did Konami leave out the BIOS because of copyright issues? That was my guess. Konami has the copyright of her own games, but if they used MSX bios code they would have to pay licensing fees to the current copyright owner (MS or ASCII?).. I found this matter interesting too, so I took the liberty of loading such a modified game into my MSX. It seems that a fair deal of the code is original. The memory layout is, the MSX cartridge ID bytes "AB" are present as are all other requirements. It wouldn't run though. However, after looking at the disassembled code, I found that it must have been heavily modified. I see JP's and CALL's to unknown (to me) addresses outside the game memory area. Also there were several unknown asm instructions (at least to wbass2) like ED D0 used in this context: ... E5 push hl D5 push de 02 ld (bc),a ED D0 ??? D1 pop de E1 pop hl 18 E6 jr h4497 Also lots of erased instructions (countless NOPs). My msx asm knowledge is not extensive enough to further investigate, for interested people i've put one such modified game online (sssh!) at: http://212.187.35.21/~tristan/ANTADV.BIN http://212.187.35.21/~tristan/ANTADV.CHT I dont know what the CHT file does, it looks like font or other graphics data.
