I have to agree, that all zx games could be better ported to MSX.

Adding main player to hardware sprite would be a must, but to adapt the zx code to do this would be a huge change, so it would be better to complete re-write the games to MSX, instead of just porting.

Also many games lost their music in the conversion...

but there's ONE game from ZX I would like to see on MSX, even without hardware sprites... TURRICAN. Even on ZX it doesnt look like a ZX game Wink

(I just dont know if MSX can have that kind of speed with only sw sprites/tiles...)

without tiles, there is a performance penalty of course, but is less noticeable.
Most depend, as you told, by the complete rewrite vs. simple port, or adaptions.

If tiles are usable+hw sprites the speed should be more and more greater than zx version.
Without tiles you need to do block move between ram/vram and the I/O based VDP access will impose a significant penalty versus the high speed native access on vram performed by z80 on zx

Looking at the two version (c64 and msx) i think the msx version could be in the middle of two, with grpx and music.

@MäSäXi: pac-land is extremely bad programmed, also for a zx spectrum game...

Indeed. It´s another reason for completely rewrite Pac-Land for MSX!

It´s so irritating to get unfairly killed again and again, just because there is no scrolling and you cannot see when ghosts are coming behind the right edge of the screen...

Arcade itself is graphically nearly MSX standard, not quite, but I mean it´s possible to make colourful background with smooth scroll WITHOUT any colour clash. (simplify background graphics a bit of course)

Watch the video of the Amiga version of SWIV on YouTube.

Don´t need to... Played it a lot on my Amiga in the nineties... :P Still remember how it looked and sounded like... almost as good as MSX port could have been... :P And we have PSG, Amiga has just sampled explosions... :P

by the way.... MSX HAS SILKWORM IV STYLE GAME ALREADY!!!!

WITH COLOURFUL GRAPHICS AND COOL WEAPON SYSTEM!

(minus jeep and BIG enemy helicopter)

AND IT HAS *SMOOTH* SCROLLING!! (well.. smooth enough... much smoother vertical scrolling than any other msx shooter has...!)

Game is Taito´s GYRODINE. (c) 1986, first Silkworm came years later....

Still, I'd just like to get it running... It seems to be extremely buggy or so...

It won't run on a plain MSX1. Though the conversion is apparently made for those machines, requires a 128K ram mapper ---so in fact, it is MSX2 only.

Also, there's a bug in initialization that makes the game randomly hang up when loading. Anyway, this is fixed in some cas image that exists on the internet (google is your friend...)

About SWIV for MSX: Reached stage 2. Bad, bad, bad game... choppy scroll and action, needs to be recoded from scratch. An MSX2/2+/turboR adaption could be similar to the Amiga version.
