Sziasztok!
Hi Levente,

Sure did!

She always brings her own to the course... At the JFK Institute they have a nice little cafe. But most of my courses take place somewhere else... So I usually don't get there in time! Anyway, there are other babes!

Yeah, that's givin' some real speed!

Is it uploaded somewhere?

I think I have those... I have coded a freq converter aswell, it's still very slow and I never really finished coding. Btw, do you know the converter routine used in "VECTOR-VICTORY" (converted by CSORY, one of my favorite demos ever)? I think the Converter was done by CSM, it doesn't use the C64 player routine but creates a TED one (kinda precalculated).
Therefore, it's REALLY fast. This routine was used in some parts of METALL ASS aswell, if I remember correctly... I have never seen the converter itself, though. Does anyone have it?

Btw, I had my last exam (US History) last Saturday and I guess I did pretty good :) I learned really hard, though. That's why I haven't been here on Friday!
> Well, what about the musics of Winter Events, Bongo, or King of Kings?
No, they suck! (Just my opinion... I like LAZA!, DIZASTERBLASTER and TERRA NOVA much better!)
> A viszontolvasasra (...sorry, I have no accented letters :-()
What does it mean? Something like "Avec plaisir"?
I think, I gotta answer some more mails...
See ya,
Christian
