The last couple of months I've been working on an MSX1 demo and its more or less finished so I thought I post it here so you can try it out if you're interested.

The demo is packed in an 512kB ASCII8 rom and I'm using an ESE RAM to play it on my MSX. I'm not sure if there are other ways of playing it. It really is best on a real MSX so it is worth trying. If you have other ways of playing it on a real MSX I'd be happy to know.

I've tested it in a couple of different emulators. blueMSX 2.3.1 runs it correctly but most other emus have some problems with it. But even blueMSX has problems showing the intial scroll as smooth as a real MSX (for the scroll part NLMSX is actually the best emu on my PC).

Anyways, give it a try and see what you think.

openMSX runs it pretty fine too Smile I think this demo should be included in the tests for MSX emulators! (if it isn't optimized for blueMSX ofcourse)

the Padial FlashG cartridge can play it as well...

Let's see if it will be a testcase for the emu comparison...

The demo is really optimized for a real MSX1 (both 50Hz and 60Hz). It is indeed a quite good test program because its doing some unusual tricks, like using sprite collision and 5th sprite detection to synchronize things. And then of course the quite uncommon screensplit (from screen 3 to screen 2) And the big scroll has issues in some emulators too (both blueMSX and openMSX) its far from as smooth as on a real MSX. Then the PSG samples sounds better on a real MSX (although its a bit noisy there too)

Yes, this seems to be quite a nice test case. On blueMSX 2.0 the screen was messed up and in NLMSX 0.48 the screen hanged after starting to play sample. (I think there is a bug in 5th sprite collision emulation)

Hope, that someone cracks this demo so, that I can look in on real MSX Tongue

Damn DVIK,

Very nice MSX1 demo ! The music sounds very clear, even with blueMSX, and the graphics rocks !
Who would have thought that a MSX1 can do this anno 2005 back in 1983 ?-)

NYYRIKKI, I've uploaded a new version of the demo. The one you've downloaded only runs on a real MSX and in blueMSX 2.3.1. If you want to run it in openMSX or earlier blueMSX versions you need to download it again (I replaced the original version). It was a bug in sprite collision when using early clocked sprites and its buggy in all emulators.

NYYRIKKI, you'd need A LOT of RAM then for that cracked version to run on a real MSX. The easiest really is loading it into a flash cartridge which has ASCII8 support... and has enough memory of course Wink

Yes, now it worked just fine in blueMSX. NLMSX just can't handle it...

Very very good demo! The problem is that I can't run it into my MSX 2 as I have not a FLASH CART. Can you put a disk version?

I like the 8 BIT MUSIC and graphic effects are impressive

Yours,

Very cool!

The only downside IMHO is the speed of the scroller - it's too slow, so it becomes a bit boring after a few minutes Wink
