I have bought a Panasonic FS-A1F with upgraded 128k mapper.
Im trying to find Konami MSX games up to 128k, like Nemesis, Vampire Killer, Metal Gear, F1 Spirit, Salamander, etc...
I have found some versions at FUNET, but they run extremely slow. Someone told me that that happens because they are PAL versions.
Looking at the Internet, I found more easy to find MEGARAM versions of it. Anyone can suggest me a website with that? The list that I'm looking is this one bellow:

Nemesis (Gradius)
Penguin Adventure
Vampire Killer
King Kong 2
Hinotori (aka Firebird)
Ganbare Goemon (aka Samurai)
The Maze of Galious
Metal Gear
The Game Master 2
Majutsushi (aka Mah-Jong 2)
Nemesis 2 (Gradius 2)
F1 Spirit
Pennant Race 1
King's Valley 2 MSX1
King's Valley 2 MSX2
Contra (aka Gryzor)
Pennant Race 2

Best Regards,

I am sorry, but asking for "illigal" content is not allowed on MRC, I don't expect you will find an answer here.

An original Konami game is shipped on cartridge which will always run, even on msx with 64k.

...all of them require only an MSX with 16 KB. Most Konamis do work with only 8 KB RAM!

Anyway, if you want to play "backups" of the original Konami games in cartridge, I suggest you to get a MegaFlashSCC cartridge. A handy peripheral!

Keep in mind that those "adaptions" have to use a slightly different mapper from the Konami one (8 k banking vs. 16 k banking). This feature sometimes affects to the "conversion": no sound, some pauses (rare)....
Original cartdriges use to be 50 Hz /60 Hz compatible, that is, if your computer is NTSC, then your game will be running 60 Hz. Try to VDP(10)=0 or VDP(10)=2 before loading to see the difference.

If the game says 64kbytes is the minimum then i thought it would not run with fewer.I do not think any msx2 machines has 16kbytes of ram.Minimum was 64 i think for msx2.Now if there is a msx1 that had only 16kbytes and was upgraded to msx2 and still has 16 then that is another story

Does anyone have an msx2 with only 16 kbytes?IF so i would like to test to see wether the game would run with only as little as 16 or 8.And what about video ram of msx?

If you have an oiriginal cartridge like metal gear 2 it can even run on a msx2 with only 64.However for disk dumps or execload or to load original roms on a real msx2 then you need usually the double amount of ram.(Example 128 kbyte game needs 256) 256 needs 512 and so on.

An MSX2 always has 64kB or more RAM, indeed. It's in the standard.

Manuel i have a question regarding the last posts.Let's say that indeed there was an msx2 with only 16 kbytes of ram.Since a z80 can address only 64kbytes of ram would not that create a problem?There is the circuity inside the cartridge (konami 8 or 16) but the z80 does know only that it can address 64 at a time and would need paging to view the rest.Would not that create problems?

So if konami cartridges use 8k or 16k blocks,does z80 in those games only address 8/16kbytes maximum at a time?

I do not think that these games could run with only 8 or 16kbytes of main ram due to the processor.
(of course i could be wrong)Smile

The memory mapper (inside the cartridge) swaps 8 or 16 kb ROM pages from the cartridge and doesn't use RAM.
So it's possible to run a 512kb game on a 16kbRAM machine (like MSX1).

Just depends on how the game is progammed (64kbRAM is easier then 16kbRAM to program).

Shalom - Knightmare III is an example of a megaROM (512kb) that runs on a 16kbRAM machine.
