Is it posible to create a cartrige on a rom?
and what will be the costs of it to produce?

and what wil be the kb that you will have?

Count me in!

its possible but in order to let them work you need a special mapper or there's also a mod for the konami cardridges but it would be nice if some body would create a kind of usb game rom do u get the picture?

PC puts the rom in the cardridge with sram via usb
and then play it on msx

its possible but the complicated things are how does the mapper work?

each type of game had its unique kind of mapper confuguration inside the cardridge

There are 3 commonly used mapperchips on MSX. ASCII 8K, ASCII 16K and Konami (either with SCC or without)

So no crap about unique circuitry please

Ese Artist's have a cartridge which can be filled with a game of your choice don't they?

ok mister nice guy no ofence

so there r 3 used cofigurations so that makes it allot easyer exept for the parts then

so it is possible to create such device

but you can make a circuit to change between the 3 mapper configurations i guess

i think it would sell much better then a gamecard reader that can result in copying msx rom games again on pc

but wich size would it need 1024KB's is enough i guess

but wich type of ram does it need sram? or regular memmory with a battery to keep the rom inside?

yep the ese artists had the mega scsi!

with 256,512 or 1024 kb of sram

but the production stoped

production of megascsi hasn't stopped.
The schematics have always been free.
I think Hans Oranje still builds and sells them.

Also, megascsi cannot be used for this purpose. You guys want either a brazilian MegaRAM or a MegaFLASH by Padial.

The latter being the nicest, because no original MSX games are destroyed in the process.

Except for Konami titles that need to be remapped to ASCII8 type and the loader doesn't have an on-the-fly conversion (yet).

I have a ESE 512k SCC MegaRAM that uses a program called NGLOAD, it plays the english version of Metal Gear 2 quite nicely

I also have a brazillian device a DDX MegaRAM, it has no SRAM but can load a ROM image from disk. The only problem is that it is 256k, does anyone know if this can be upgraded to 512k or more ? Then I can play Metal Gear 2, and R-Type

On MSX Files you can find a R-Type for Megaram that works on 256kb MegaRAMs =)

BitWize are buzzy whit that kind of stuff

Is is also possible to make a real game ROM. Like in the old Konami days? Have prices gone down enough to make this 'commercially viable'. Or better yet; viable uncommercially. Is PROM still used, and is it even cheaper than EPROM? Or is all of this too expensive to even begin to consider?

Jhea but how do a game what exist of a lot of files?
