Yes, My SNATCHER and KONAMI game Collection vol1 are the ORIGINAL KONAMI games(KNIGHTMARE,KUNG FU,KUNG FU2,ANTARTIC ADVENTURE use the SNATCHER Sound cartridge) comes with another unprotected disk with King's Valley(Level editor version).
I buy for $150 used.But the Snatcher Sound cartridge is the only Konami really SCC cartridge for disk games.
The SD Snatcher you need to modify to RUN games.
The Snatcher is expensive but the GC's are only $50 and use the Snatcher sound Cartridge.
GRADIUS 2,F1 SPIRIT and other games for MSX1 are cheaper to!
I WANT the Namco disk with PACMAN and others.
Japanese music programs and one game use the Snatcher SCC to!(Not work with the SCC from MEGAROM games like Metal Gear 2 and others)
Exist some Music Drivers for OPLL(FM),PSG and SCC.Like the Japanese MSX Magazine MuSICA(17 sound channels) and MGSEL both excellent for play music's, even better than the original music from MSX games ...
SNATCHER,SD SNATCHER and METAL GEAR 2 SOLID SNAKE are some of the most expensive game NOW.
The original price of KONAMI games are from $45 to 95.But some people sell these games for 80-150.
They are a lot cheaper in JAPAN a 10 years.
I know two programs that use the TAPE INPUT.
One is for SOUND digitalization and another for SPECTRUM Analyzer both for MSX.
And OF COURSE these programs are NOT in the NET.
