I'd like to express a wish :
I'd like to see some games ported to MSX system.
and some others to be improved and like originals ones.(when possible)
I mean , In the 80' I played a lot with Popey,Charley Circus,Iron horse ,Mario Bros, Green Beret,Gyruss..... standing in a bar or a videogame room.
I played Some of them with MSX1 version and I did like them , but since MSX2 came out I have been keeping on wondering if something better could be done
No matter if it requires 128k and use of diskdrive .

Theres not a person who could say that '16kb ought to be enough for everyone' .. the biggest computer-industrial tried something similar in the 80's.. he failed deeply. Tongue
Actually, he didn't.

In any case, you got the point, rite?

Hi, I just have a little question I hope you could answer for me. I have a prototype game for Nintendo which, instead of having PRG and CHR eprom chips, uses one PRG eprom and one VRAM chip. The prototype was originally ported from the famicom disk system, so the graphics had to be manually copied from ROM to VRAM. When I open up the ROM image in Tile Layer Pro, the graphics appears "shifted" or compressed. I would really like to be able to decompress the graphics to see what it contains. Anyone knows what can be done? Very thankful for any information!

This is highly offtopic (you're better off asking Nintendo questions at!

If you can get the game to run in an emulator that has this feature, you can export/dump the pattern table data (the tiles currently being used) to a file. I know Nintendulator, for example, has this feature when debugging is enabled.

Now, if you can't get the game to run, and it processes the CHR data somehow (decompressing or whatever) before sending it to VRAM, there is no way to rip the graphics from the ROM unless you know what compression/coding was used. You'd probably have to study the decompression routine for that.

Can't we just drop the MSX1 thing? Please also include MSX2

I think that MSXDev should stick to the MSX1 tech specs

Why? Aren't the current MSXdev games not good enough. And have you ever wondered why this contest is a succes?

I think the specs need to be set based on the contests goals. The goals I read between the lines in these posts:

- Having a contest for the sake of having one?
- More games for the MSX?
- Keeping the MSX alive?

The problem is that everybody has one of those goals in mind and react according. For me it would be goal nr. 2 and with this in mind the only limits I would see is not allowing external hardware to run a game. But I think the people who participate do it for goal nr. 1. Why do I think goal nr.1 because if it wasn't they would make games outside the contest. But here a problem arizes because some people make a game alone and others in a team, also not everybody is skilled to keep the game small (in bytes) or in getting the max out of a MSX1. This results in a conflict where the skilled teams can use less resouces (read: less bytes) to do the same a less skilled person.

I hope somebody did understand something I am trying to tell Wink
My vote would be splitting the contest in 2. One with limit resouces like MSX1, limited bytes. And another with MSX2 and loads of bytes. But one thing should be 'not done' is allowing external hardware (like SCC) in order to be able to play the game.

And what is such an SCC is only a bonus? e.g. the game will run without it?
