Hi all !!

For a new game I am thinking about using a 1MB or 2MB rom cartrdige, instead of a 512kB one. But where can I buy them ??

cheers

Just add 2 or 4 512KB roms!

First code it. Then look for a solution.

norakomi: in these days of bitbust -and since it's ROM: no loading time- what kind of game are you talking then eh? What's in it? FMV?

It is Manbow3!

I basically have a very big game in mind, hahaha.
with manbow2 I managed with bitbusting and 512kB,
but the whole rom is packed.
For a new game, which is simply gonna be bigger than manbow2,
I need a bigger cartridge....
But,
if this is not available, then this leaves me no choice but to make a 512kB game......
all help is welcome....

The AM29F040 is used in several MSX hardware projects, including Nowind. It is 512kB and quite cheap.

Erm guys
@Kwik if he needs bigger than 512kB ( is equal to the chip you mention namely a 4 megabits flashrom) it doubles everytime , namely to 8 megabits like tghe kOEI GAMES, 16 megabits needed for if one wants to do it bombaman , and e.g. paiii and tlw need a 32 megabits rom
@pitpan very wise solution indeed since it is not that simple as saeba suggests

Note that those chips are quite expensive , but yah you can find them although farnell has not bigger than a one suitable as 8 megabits

Why not make it a hd game?Many msx users have sunrise ide or cf adapter,so in that way you are not limited by the size of a cartridge.Also add a quit to dos option in the game and all is fine

(just a thought)
Best regards

I was just joking, I do know that it is not that simple! But, in fact, it is possible in this way, but of course more than adding chips have to be done.

And I agree with you, first code then ask. Delivering games in CD/cards would be wise too, as Delta Soft made in the past.

I dont want to make a ONLY hd game, because then only people with a hd can play the game. I prefer a cartridge release.

my experience with manbow2 is that "first code then ask" is a bad idea.
Because manbow2 uses saving to rom and scc.
Which means that when the game was finished I had to look for someone who could release the game for me on a flash rom with scc......
And thats exactly the reason why manbow2 is still not released... and it will take quite some months before it WILL be released....
So, NO, I don't want to make the same mistake...
That's why I FIRST want to know
* what kind of hardware is available
* where is it available
* how much does it cost
So if I cannot find 1MB or 2MB cartridges, then I will NOT program for it.
I prefer: "first plan, then code"

Afaik, Manuel Pazos built 1MB flash carts (I don't know if they were sold though). The problem is that using 2 512KB Flash makes that no free space is available for extra SCC or SRAM. Of course it could be done in bigger boards (as IDE), but for a game it is not that nice.

I also saw in the last Barcelona meeting a version of Monster Hunter in cartridge. It was megarom with SCC built in. Why don't you explain the reasons because you couldn't find anyone to make it for you? I saw it could be easily done!!

Cartridge is the best format by far. The success of Matra's Shockware relies on that fact.

Quick Disk: No comments
Laser Disk: Does anyone own a Laser Disk burner (I know the answer: Pioneer )
Tape: Abandoned in the late eighties/early nineties
Disk: Not every MSX1 (nor MSX2!) has a disk drive
CD: You need a SCSI or IDE interface and only a few hundred of people own them
CompactFlash card: You need Sunrise's CF interface
Cartridge: Present in 5 million machines

oh, add the plug&play factor

PC with an emulator and all these 'problems' disappear as snow on a hot summer day. The best format is files: to be put on disk or tape or whatever media you like...
