It uses to much ram from page 3 to run it from disk. On passionmsx there's a cas version which you can try with an emulator, after booting with shift

@ro: it works on the real thing, I double-checked, so there's nothing wrong with the files.
And the link to the proper video:

scene in the past, and all I've seen are Bandwagon/Lievestoure's demos.



Yes and no. Yes, there are active people around, they're these days mostly aiming at games and other things (emulators, xdev tools, music, websites, etc.) So, no, regarding demos you can't expect something like a typical scene like on other systems (PC, Amiga, C64, Atari etc.)
Apart from the activity difference, there's also quite a style difference. Your demo, and those of Bandwagon, are quite like what demos are these days, or what they were on PC's in the early 90's. The MSX demo-history in the 90's is basically oldskool all the way. 'Scroll and Logo' demos, one might say that the MSX-scene was quite a bit conservative and perhaps 'simple' even. Far into the 90's we were still reading long boring scrolltexts with greetings and anti-greetings, a repetitive tune of 2 minutes, some ripped Amiga font, and prolly also some ripped logo above the font. And ofcourse the standard effects like (sine-)wavescrolls, copperbars, bouncing logos, stretching images etc. Basically everything related to screensplits, palettes and scrolling. There's actually only a handful of demos I could mention which are exceptions on the rule. Between all our oldskool things, the Bandwagon things are completely alien, and so is yours..
Since some years people start to focus a little bit more on newskool, but I could again only mention a handful o' things, and in many cases it's not even realtime! Making (MSX1) games seems to be the most popular activity these days. Note that the most advanced gfx-chip on MSX has 32768 colors, multilayer, fullcolor sprites, scrolling, 512kb. The most advanced soundchip is an OPL4 chip (24 wave channels, 18 FM channels). Most recent games and demos however have been for MSX1 with PSG. On many aspects, the MSX and its people deserve the international oddball-award..

Another difference between the MSX scene and other scenes is the lack of gfx-artists. In demos on other platforms you usually see a random picture after a while, during some musical break orso. Not on MSX, the only graphics are mostly not related to real art but to technique, e.g. a font, a logo etc.

you might want to check out the download section, check out demos and the MRC challenges section. These challenges brought us some recent demos 'n things (tho the last really big challenge dates back to autumn 2004 iirc -Bounce-)

Perhaps he means better tweaked timing for mid-scanline VDP writes. If so, does that also fix the scrolling glitches in eg. Circus Charlie and Alpha Roid? (or are those glitches normal? I've never seen those games running on a Japanese MSX1). If it's not based on guesswork, or unrelated to such timing, I'm interested in the details too

@manuel: The problem is that when writing vdp registers the vram pointer is modified as well. On MSX2 its not. I found and fixed this bug only a couple of days ago when working on the sequel to MSX Unleashed.

There is one group that is quite active with a couple of MSX1 demos already released and more coming. The group doesn't have a name though but its me and Vincent. The most interesting demos are probably MSX Unleashed and Waves. You can find both demos at youtube too if you just want to see them.

dvik: thanks, I ported that fix to openMSX and it shows a lot better output indeed.

hap: what glitches do you mean exactly in those games?

esau: are the lines in the background of that Traktor logo indeed supposed to be dotted? They show up as straight lines in our emulators.

Note: on a real MSX1 it showed straight lines, not dotted lines. So it's probably the video making them seem dotted.

Hope you don't mind; here's a disk version for those with a MSX1 with diskdrive, like me
download here


hm.. this fails on my msx1, but works on my msx2?
