Advancemame with svgalib support

[taromaru]

Hi folks

This is my first post here so first of all Ii would like to thank all the gentoo the users for making such a community and providing almost every bit of info I need for setting up a fast and useful system

I have everything I need up and running, but now I miss playing mame. I have merged succesfully xmame and gxmame and actually can play roms with xmame, but I would like to take advantage of the profits advancemame gives.

I compiled two kernels from nitro sources, one with compiled in vesafb-tng fb device and another one with radeonfb for my old ati radeon7500. I read somewhere in advmame doc that games should be playe using the cards fb device.

dmesg show yesterday some lines about radeonfb but right now I cant post them because dmesg is flooded with iptables info (?¿)

I also emerged svgalib and configured my system to load svga_helper on reboot. I also edited /etc/vga/libvga.config reflecting my monitors horiz and vert refresh with the values I get using xvidtune.

I then edited advmame.rc and advmenu.rc pointing romdir to my roms directory and setting my monitor specs with
device_video_clock 108 / 30 - 80 / 50 - 120


When I try to start some game I got this error:
...
svgalib: Failes to initialize mouse (I dont care much aout this at the moment)
No video modes available for current video game
Unable to start video emulation
kevorkian@kevorkian ~/.advance $

It seems to be an issue related to some of the config lines in advmame.rc.
IMO device_video_modeline and device_video_format are the ones to edit. But having already read how to edit this lines in the official documentation, I cant figure out how to change them for my monitor.


From the advdev doc:

4.2.2 device_video_modeline
Define a video modeline. The modeline format is compatible with the format used by the Linux SVGALIB library and by the XFree Window system.

device_video_modeline Name CLOCK HDE HRS HRE HT VDE VRS VRE VT
[-hsync] [-vsync] [+hsync] [+vsync] [doublescan] [interlace]

Options:
Name Name of the video mode. You can use the quotes '"` for the names with spaces.
CLOCK Pixel clock in MHz
HDE HRS HRE HT Horizontal `Display End', `Retrace Start', `Retrace End', `Total'
VDE VRS VRE VT Vertical `Display End', `Retrace Start', `Retrace End', `Total'
-hsync -vsync +hsync +vsync Polarization mode.
doublescan Doublescan mode.
interlace Interlaced mode.
Examples:

device_video_modeline tweak320x240 12.59 320 336 356 400 240 \
249 254 262 doublescan -hsync -vsync

4.2.3 device_video_format
Select the format of the video modes to create. You can insert more than one of these option.

device_video_format HCLOCK HDE HRS HRE HT VDE VRS VRE VT

Options:
HCLOCK Horizontal clock in Hz
HDE HRS HRE HT VDE VRS VRE VT Like the modeline option
When a new modeline is created, AdvanceMAME uses a linear interpolation of the two formats with the nearest horizontal clock.
The default value of this option is for an Arcade 15 kHz monitor:

15720 0.737 0.075 0.074 0.113 0.916 0.012 0.012 0.060

and for an Arcade 25 kHz monitor:

25000 0.800 0.020 0.100 0.080 0.922 0.006 0.012 0.060

and for a VGA 31.5 kHz monitor:

31500 0.800 0.020 0.120 0.060 0.914 0.019 0.004 0.063

Which one of these defaults is used depends on the setting of the `device_video_clock' option.



It seems there are no examples for a home use multisync monitor. I dont fully understand this documentation.
If any user over here has alredy set up advmame using svgalib in a typical 17 inch monitor, any help will be welcome.

If you could post some lines of your rc files I could keep trying out.
Also, any suggestion is welcome, I dont care about having to recompile once again a new kernel, I just want advmame&advmenu UP AND RUNNING

Thanks in advance,

Agur!
