Another technical-ish topic:
quoted from msxnet.org: http://www.msxnet.org/tech/megaroms
This is a 32Kb ROM cartridge from Sony. Supposedly it has a DAC. All I could find in the source was a few writes to address BFFFh, in it's own address space. It's also reading it. Since it's just a few bytes, seemingly ranging from 0-7, it's not a normal DAC. What this address actually does is a mystery to me, any help here would be most appreciated.
I've seen this game running once at an MSX fair, and it does have a DAC on board which plays several samples during the game (eg. speech, and when you hot the ball with your bat). I've looked at the contents of that game a bit, and haven't found any sample data in the ROM itself.
The only possible thing that's left is that this game has an extra ROM with the samples. It's fairly easy to conclude that the number that it writes to the memory I/O port BFFFh is a request to play a sample.
Does anyone have the cartridge of this game to look if it has a sample ROM in it ? And maybe even dump that ROM (it's probably not possible with programs like saverom, but it should be with an eeprom reader device).
Or maybe someone can prove me wrong here ?

. I'll try to have it emulated in next version of blueMSX.
