Unless, of course, you care about perfect emulation.
This error means Meka couldn't display all the colors required by the game.

Why is my 32000 colors buggy?
It's not my fault that Meka can't display all the colors and BrSMS can.
As a matter of fact, there's NO WAY to display all the 512 game gear colors on 256-color display,
so that's why I use the 15-color mode.
I can make a game gear rom display all the 512 colors at same time, if you want to see it,
but of course you will need BrSMS for that.

Right for some games that truly act a weird way with the palette.

Actually, it's not *your* 32000 color mode that is buggy. It's 15-bit color modes in general, many video cards do not support them correctly.
Well, last time I tried BrSMS with that feature (for.. I don't remember, most probably Super Monaco GP 2) I had very weird colors.

Theorically right, but in fact no games would have all of them displayed on the same time.
That's why a dynamic color management do the work nicely (and faster than a hicolor mode)

Then I suggest using a 16-bit mode and it'll rules ^_^

I do have all versions of BrSMS still unzipped :)

Same over here as well. 16bit is a more standard mode. Move to this mode and Zoop can't call it buggy anymore :)

Cool, go for it. Need more public domain SMS games.

even 16-bit mode is weird on my card... i always end up using systems with shoddy VESA (2+) support... my current computer (with a creative labs graphics blaster exxtreme value.. ran me $25 or so six months ago) has never been happy giving me any VESA modes but 640 x 480 x 16 banked, and the free GB Exxtreme-specific version of SDD they gave me caused more harm than good.
As usual, the win32 display driver and directx driver work flawlessly or near flawless for the usual range of resolutions that I'd love to have in DOS...

...which brings me to and idea that I suspect might deserve a thread all to itself:

I'm surprised that nobody (to my knowledge) has endevoured to write a dos-wrapper (or emulator, or... I'm not sure what I'd classify it as..) that would remap VESA support, video card access, and sound blaster through directx drivers, so that video and sound cards that have shoddy dos drivers (most of them, these days) could be used to their maximum potential.

Sitting here and thinking about it, maybe I understand why it's never been done... maybe the sound blaster support is a bit too much to ask, intercepting port access would take no less than some sort of dynamic recompiling system (although the 'recompiling' part isn't so difficult now is it? hmm, 80x86 -> 80x86 minus port access).

So far as I know (I never dealt with it directly in my dos programming days) VESA support doesn't require any port access..
However, I would guess it does allow free access to video memory with the pointers suppied by the driver, right? DirectX gives you direct video access, but only while the display memory is locked, and that should only be for a brief period of time..

Oh hell, I'm in over my head again. I just wanted to use these meka and brsms with better video support and 44.1khz sound reliably (I also get stuck with crappy sound cards which won't go over 22khz with dos drivers.. ever. of course I only paid $7 for the last one, which declared on the box, in broken english, that it was Windows 97 Compatible).

Yeah, I came up with a few simple sms demos that used a lot of raster tricks, and brsms ran a few of them that meka didn't, although I haven't tried it on newer mekas...

I'd have gone further with sms coding but I've gotten spoiled on C and on cpu's that can do multiplication by themselves. Lazy man.

BTW, thank/damn you to Ricardo Bittencourt and Zoop/Omar(is that two people or one?) for giving us the best emulators and continuing to innovate. ('damn' because I wanted to write the defacto best and most loved SMS emulator, but I never did it because I'm lazy and stupid... well, maybe I can write the best win32 sms emulator if I hurry).

Heh! Why didn't you release your demos? The Development section is awaiting for them :)

It's one person: Omar Cornut = Zoop

Maybe I will, if I can get them working again. I left off several months ago with only a work-in-progress version that doesn't really work anymore, and damn me I didn't comment anything whatsoever.

Thought so.

Who cares if they work? Go and release the damn things :P
