Thank to the feedback.

New version with Playsoniq support! Do not connect the Playsoniq to a monitor. Only the sound chip is used.

Working ok :)

FLASHPOINT (but too fast?)

Strange, All 1 player games work exactly as on a real NTSC SG-1000 if your MSX run at 60hz.
The 2-players games using a routine for joysticks but I noticed no slowdowns.

These games are not supported because it still exist on MSX. They are identical except the sound for some games. The sound is a bit corrupted on conversion from MSX.

I know just wanted to try them anyway Smile

Some results for SG-1000 games... I tried some that have problems using SG2MSX:

Work but controls not working:

BOMBERMAN SPECIAL
THE CASTLE
TANK BATTALION

Not working:

KNIGHTMARE
THE LEGEND OF KAGE
RALLY-X
ROAD FIGHTER
TWIN BEE
YIE AR KUNG-FU II

Even if they are ports from MSX, it might be interesting to see them running because most are from Taiwan/Korea and they have different title screens.

I will try more later.

What is your configuration?

Can you try the following games?
- Space Armor
- Rock'n Bolt
- Safari Hunting

These games work on my MSX1 but bug on MSX Turbo R (they work on MSXblue). I need help.

NB: Now SG1000.COM is totally different of SG2MSX. The loading is faster and patches are individual for each game. Also the interruption routine is not modified. In return SG1000 can not load the single ROM of 48KB that exists (to my knowledge).

My real MSX is an MSX2 TPC-310 with 128kb RAM, 128kb VRAM and DOS 1.
I am trying both on the real machine and emulated machine (similar setup but more RAM and DOS 2).

All results on emulated system:

Version 0.6:

ROCK'N BOLT (doesn't work, displays scrambled title screen and hangs)
SPACE ARMOR (doesn't work, displays garbage)
SAFARI HUNTING (static title screen, no controls)

Version 0.8:

ROCK'N BOLT (works)
SPACE ARMOR (works)
SAFARI HUNTING (works)

An interesting remark about THE LEGEND OF KAGE.
It used to work (except for controls) on v0.6 and now hangs (v0.8).

Other 48kb roms such as BOMBERMAN SPECIAL and THE CASTLE seem to work except for controls.

If you are interested in these results on real machine, I'll try later today.
But as far as I know, no differences between my real machine and emulated one.

In fact I'm only interested in tests on a real MSX and only with listed games.
The games that are not listed do can't work correctly because the corresponding patch do not still exist.

PS: SG1000.COM can't load 48KB Roms. It's 40KB max.

Tried on real MSX with version 0.8, results were the same (all games work) but ROCK'N BOLT has some graphic problems.
It would be awesome if you add more patches for the games that don't work.
By the way, how does the patching work? (ie. How is each game recognized?)
About 48kb roms, as I said, some work but have control problems.
Try for yourself, THE LEGEND OF KAGE or THE CASTLE.
Let me know if you want me to do more tests.
Thank you.

Thank you for confirmation. Space Armor has no problem sprite? Safari Hunting is playable?

I work for that but for the first time I prefer to focus on the original SG-1000 games and their different versions.

The following games work also on MSX without any modification.

C_So! [MSX] (KR)
Comic Bakery [MSX] (KR)
Cyborg Z (KR)
Eagles 5 (KR)
E.I. - Exa Innova [MSX] (KR)
King & Balloon [MSX] (KR)
Mopiranger [MSX] (KR)
Magical Kid Wiz [MSX] (TW)
Rally-X [MSX] (TW)
Road Fighter [MSX] (KR)
Road Fighter [MSX] (TW)
Sky Jaguar [MSX] (KR)
The Castle [MSX] (TW)

You can try on a MSX emulator if you rename file extension by ".ROM".

The two following games work on MSX if you remplace a single byte with a hexa editor.

Pooyan (Hi-Com) -> Remplace the byte 80h by 00h at 4005h address
Galaxian (Hi-com) -> Remplace the byte D0h by 41h at 4000h address

Safari Hunting is playable, yes.
And Space Armor has flicker on sprites but is playable too.

I tried some of them and they do work on emulators, but on MSX, using execrom, they don't... I haven't tried converting them to binary yet.
