Hi there !

I'm fed up with two games who don't work on my CF. It's SD Snatcher & Metal gear 2. Of course, it's the image disks of SD and the English rom of MG2.

Here comes my config:

Turbo-R GT @1mo
CF 128mo @FAT12
Multimente, dos2.30
For load the roms, I used Loadrom / Megamu.
For the dsk, FD.com or start.com

I've tried HDDemu with my original Japanese disks from SD without success.

If somebody has a clue, it will be soooooooooo great !!!

Thanks in advance & greetx,

SD Snatcher works with START.COM, you just need to run MAP.COM before you start it. Works fine on my very similar system.

SD Snatcher has copy protection. So it will not work if you dump directly from your original disks. Furthermore, I don't know if HDDemu can run that game. I use EP.COM (MegaSCSI, MegaSD, OneChip) and works great.

About Metal Gear 2. In this post SLotman has problems running the game with an external mapper. Have you tried the DSK version?

Thanks guys, I've tried this but with Map.com & Start.com nothing boots.
I've tried with Map.com & FDE.com, it boots but it freezes after the SCC port menu...


EP.com is designed for Megscsi only, isn't it ?

I'll take a look about SLotman's problems.
Thank you very much !

I think the best think i did was to purchase a megaflash scc from Manuel Pazos in order to play the rom version and not mess with the disk one.However since in my msx2 i have a 4mbyte memory mapper Metal Gear 2 martos's crack version works ok.I think there must be some utility out there that does the slot switch in that way you can change the memory mapper you want instead of the original one..I can't remember the name of the program though.For me megaflash scc was the best to play games with scc sound.

NYYRIKKI posted this program in the thread manuel mentioned (NYYRIKKI you are great programmer!

10 'TEMP.BAS
20 SL=1 'SLOT
30 IF PEEK(&HF677)=&H80 THEN POKE&HF677,&HC0: POKE &HC000,0:RUN"TEMP.BAS"
40 FOR I=0 TO 11: READT: POKE &HD000+I,T: NEXTI
50 OUT &HA8,192+SL*16: OUT &HFE,0
60 DEFUSR=&HD000: A=USR(0): OUT&HA8,SL*80: POKE &HFE,1
70 FOR I=0 TO 3: POKE &HF341+I,SL:NEXT I
80 DATA &H21,0,&HC0,&H11,0,&H80,1,0,&H40,&HED,&HB0,201

then if you are under dos 1 you need to

POKE &HF346,1:_SYSTEM in order to load metal gear 2 since it has a sector loader.However if you do not want to run metal gear 2 disk version just run this basic program then go to dos and load it the way you know with loadrom etc.It should work ok!

I used a version with copy protection removed. As I said: works fine with START.COM and MAP.COM combined.

Hi, I notice that your MSX turbo R is extended to 1 MB. That might be the problem cause. Reading back the mapper ports (like is done by map.com) only works well for the first 512 kB. If you go above, it wraps (it is a design flaw in the turbo r). So when you have 1 MB and you have started in MSXDOS2, MAP will crash your MSX turbo R, as DOS2 will become confused about which mapper page is active in which address range.

Have you already tried under DOS1/diskbasic-1?

Thank you very much guys for help but nothing works...

I've tried with the basic program, it freezes.
I've tried under DOS1 with MAP.COM and START/FDE.COM, it's the same.

I've tried with my original images disk from SD and the English ones. Unfortunately, I haven't dsk with copy protection removed for test.
And for MG2, I'll try with Japanese and English rom (version1.2 too) and the dsk image.

I haven't try with TRload.com
I haven't find it by now.

If you still have a clue...

Anyway, I'll test all tomorrow with my ST@512Ko.

If somebody could send me files, here comes my adress:

Thank you very much !
