hello!
Just a question: Why games running in R800 doesn't alter/distort the music and running in 7mhz yes? (sorry about my english)

Because the R800 is a proper hardware extension while 7MHz is not.  The turboR has a separate clock signal for the PSG/MSX MUSIC etc... Since this is not the case with 7MHz computers the sound is distorted. I've heard of people who 'corrected' their sound hardware, but I don't know if that's possible with the PSG too... |

Actually I would prefer to say that it's more a hardware design error of most msx soundcards. Using the cpu clock as a base frequency for tone generation is not very smart. Good thing the opl4 has it's own clock.  |

hm, well, but then again it wasn't the original idea to have your MSX running at 7mhz....
Speaking of which... what's people's opinion on modded MSX'es? Accepted, cool, or "not done" ? I mean, there's a difference between internal modifications and add-on carts; add-on carts are usually ok, they don't alter your msx, but mods, well...it changes the hardware itself.
Just want to know what ppl think of it.
