Well, in any case, keep up the good work and most importantly, having fun with MSX

For sure it's great news that there's not only a coleco->MSX porting scene, the Spectrum games database is huge and in some cases of great quality. Doing such quality work I hope a lot of excellent conversions will come.

My suggestions: Green Beret (the Spectrum version is the best one), Dan Dare, Cobra...

this is the list of other systems candidate for new ports.

Coleco is the closest to MSX
But also SMS could be a good source of new games, eventually for msx2+

What about the SC-3000? Any decents game left for conversion? Sometime ago, we got a nice conversion of Zippy Race/Traverse USA.

Zippy Race? best conversion evar

Nice GNG port Fudeba! Even with frameskipping, the gameplay remains good.

Thanks very much Fudeba for this GREAT conversion. I must try it also to see if it works under the One Chip MSX and also at 10 MHZ ^-^

Thanks again!

Really NICE conversion! , I like MSX native games, but the speccy conversions really bring me memories. My suggestions for next ports: Rod Land, Golden Axe, Street Fighter, Rainbow Islands, Pang, Chip's Challenge... /me looking for the release of a tutorial about how to make those speccy ports!

Is it possible to port those games (For example Rainbow Islands) to MSX 2 and add new Gfx? For Rainbow Islands I am willing to make new Gfx. Just gimme the speccy Gfx in screen 5 format and I will redraw them.

And no, I don't do MSX 1 graphics

Just wondering...
how difficult would be move a speccy game to screen 5 ?
pixel actions could be mapped to vdp commands... or not ?

As long as individual sections of the screen aren't moving on their own and in their own direction, it's probably doable.

Still, I feel people are seriously underestimating what one can make with pattern tiles. Just run Space Manbow, look at the in-game graphics, and tell me they suck..

Commando, Bionic Commando, Roadblasters, Space Harrier, Space Harrier II, E-Swat, Out Run (yes, Outrun on Speccy looks very close to the MSX1 version, but it's far better in every aspect), Turbo Out Run, Buggy Boy, Super Hang-On, Super Monaco GP, New Zealand History, Operation Thunderbolt, Ivan 'Ironman' Stewart's Super Off Road Racer, Cabal, Bonanza Bros, Dynamite Düx, Silkworm, Turbo Espirit, Sidearms, Forgotten Worlds or P-47 have also 48K version ... FOR EXAMPLE

Strider or Pang are only 128 KB.

I plan to do 128 conversions too (in fact, the difficult is almost the same) but then it'll require memory mapper (128K, since I know no MSX with 80KB, 96KB or 112KB). Of course in some cases it is possible to make it work with less RAM, but it is not always easy: when using less RAM it requires disk access... and when it requires disk access, it requires space to store BDOS data (usually the are D800h ~ FFFFh), which take away the extra memory we have on a 64KB MSX.
Anyway, I'll always try to make the requirement to be 128KB of mapper, but *not* MSX2 (since it is possible to run MSX1 with mapper with minor changes on the ROM).

It is the way to implement a "SWITCH" clause in Z80 ASM. It is done the following way:

in C:

switch B:
{
case 1:
do this;
break;
case 2:
do that;
break;
default:
do whatever;
break;
}

in Z80 ASM

; switch - B has the value
case1: DJNZ case2
; do this
jp endswitch
case 2: DJNZ default
; do that
jp endswitch
default:
; do whatever
endswitch:

Note that DJNZ is used to jump forward, and not backward (as usually is
done in loops). It's a pretty common trick on the Konami games, but not
common on other companies' software.
