@Spirantho

As espected is very slow on my Sam440 Flex, however using this 0.148 i didn't note any slowdown compared to the old 0.146, they are mostly 1:1 ... atleast with my gameset

Still also the old DSI crash, this happen from time to time expecially if you try to start it from the binary icon instead of the icon launchers

Mame will start after that so you can ignore the error and continue, however a fix for this crash would be better

Also how about suppressing the shell output, even with a simple tooltype option, like for example: (SHOW_OUTPUT=ON/OFF)

Overlay gives much better results in that regard.

Yeah on my Peg2 on OS4 Mame is quite fast enough for my uses. It plays all the roms i have full speed. I do have to say its nowhere near as fast as the Morphos version.

@thread
Where can i read on line about what roms are compatible with what versions and how to get them? Thanks

@realize

I didn't refer to the 0.148 OS4 version, btw. I wouldn't dare testing a SDL version, even on Pegasos2. MAME is slow enough, no need to slow it down even more.

@samo79

Can you tell me what your stack is set to please?

@Fab

The main difference on there is probably the L2 cache.
My 600MHz 440ep can run Pang with no video at 102%, so I'd expect a G4 Peg II to be a lot faster than that.
The problem is verifiably in large screen sizes because increasing the screen makes quite a difference to the frameskip. OpenGL will help with all that because all it'll need to do is to render to a surface and the main bottleneck will be gone. I don't see why my Sam wouldn't be able to run without frameskip as rendering to a texture will be not much slower than no renderer at all, and the Sam's graphics core is easily capable of drawing a single polygon with minimal overhead.

I still stand by what I said, though - to compare MAME on a Peg II to MAME on AROS x86 to MAME on a Sam, you need the same build parameters; without doing that there's all sorts of other overheads such as SDL which will affect things massively. If you were to do a build of MAME 0.148 on a G4 Peg II MOS machine using the basic build parameters, you'd get a better comparison - obviously the Peg II would be faster, but not by as much as many would think, I suspect.

Really, though, the Sam isn't a good machine for emulation because of the lack of L2.

Edit:

The thing to remember about my porting SDLMAME is simply that I don't have the time for a properly Amiga-ised build. I figured better to have a slow version than no version at all. :)

@Spirantho

Both launchers (MAME and MAME_Windowed) are set with the follow stack

Quote:

stack 2048000

Instead the main binary is currently set at 32768 (default).

I also tried to increase the binary stack from its current 32768 value to the same stack number used for the launchers (2048000) but it crash on the same way ..

Very odd. I wonder why ioport is crashing... and how it's continuing afterwards?

MAME needs a proper maintainer really - I'm more of a compiler. :)

Do you mean what happen if i ignore the DSI ?
Nothing, MAME start normally and continue to work fine, however the system may become instable after a while because the previews crash .. that's why i report it

@realize Don't forget to configure the inputs to use the joystick :) Do it in the menu where you define your keys, but use the joystick instead of pressing a key.

I hit TAB and tried to move the joystick and press buttons but no input response.

@realize

You need to use the keyboard to go the key entry for Up/Down/Left/Right/Fire and redefine them. When you get to the key setting you want, press RETURN and the normal key binding will disappear. At this point, move your joystick or press a button.

If your display resolution is set too high (i.e. your SDLMAME_DESKTOPDIM is too large or not set) you may find the menu response is very slow - try it with the display much lower.

Why we need recent versions of MAEalso if we cant use them????????

For anyone who's interested:

I've uploaded a new version here:
http://www.retroreview.com/iang/mame_0148u1_ogl.lha

For some uses this may be slower, but generally it's faster. It's only a temporary OpenGL build, but it's better than nothing. When we have proper OS 4.2 it'll be faster; MiniGL doesn't support the format MAME uses so I've put in a texture endianness-swapper before it uploads the textures.
The net result is that it's slower than software renderer when you have a very small screen, but scaling is now basically free.

You'll notice a substantial increase on some games and less so on others. If you have a large screen dimension, though, you'll notice a potentially much larger speed.

To use the OpenGL, use:
mame (romname) -video opengl (-w) (-nosound)
If you want to use the software renderer, use "-video soft"

Alpha'd textures don't work yet but this doesn't affect anything except making the text hard to read.

Obviously you'll need an OpenGL capable graphics card. :)

@Spirantho

Tried from shell but it seems i need to remove part of the command line:

This one "(-w) (-nosound)"

because with that i got this error:

Quote:

Error: unknown option: (-w)

So at the end i start my game with:

MAME (roms/sf2ce.zip) -video opengl

And it works but only in fullscreen, it seems a bit faster with sf2ce (Street Fighter 2 Champion Edition) however not playable on my Sam440 .. as you say still also some graphics glitch on the text

@samo79

I meant that the -w and -nosound parameters were optional, I can't use square brackets in a forum :)

I.e.
mame Ghouls -w -nosound -video opengl

to run Ghouls 'n Ghosts in a window with no sound.

@Spirantho

Ok it works now, ssf2ce (Street Fighter 2 CE) is running fine on window now however still the usual DSI crash when you execute it from the main binary

As you can see i renamed the binary as "MAME_GL" to not conflict with the script that use the same name, for the final release maybe you might create another script in order to start MAME with OpenGL enabled by default

Aniway here is the shell output i got running the game:

So to sum the problems we have currently are:

- The DSI to fix starting MAME from the main binary
- Adding an automatic script also to start the emulator with OpenGL enabled
- Fix the color issue on the text starting MAME with OpenGL enabled
- An option (tooltype?) for suppressing the shell output ?

You can always
set HOME=RAM:
to get rid of those warnings. And you can run
Mame >NIL:
as well if you want.
If you don't have a Catweasel but still have the AmigaInput driver you may want to delete that from libs:AmigaInput (just in case).

Not sure what else to suggest to be honest as it doesn't happen here....
