crt-pi shader users - reduce scaling artifacts with these configs in lr-mame2003, lr-fbalpha, lr-nestopia (and more to come)
-
Dankcusions, im lost when it comes to linux etc, can you please create some shaders (H & V) for my 1600x1200 display?
-
just to flag that i'm aware that these configs don't work with current retropie/retroarch, due to
aspect_ratio_index=22
no longer being the right setting for the 'custom' aspect ratio than the configs require. this is due to a change at retroarch's end: https://github.com/libretro/RetroArch/commit/8a63ace201233256672241346b2a67a7c0d372f8#commentsi'm currently in discussions regarding this, and will update my script when a resolution (hah!) is reached: https://github.com/libretro/RetroArch/issues/7536
i would also like to support the latest fbalpha version properly, but i think i need @UDb23 for the appropriate resolution-db file ;) i can vaguely remember how to generated the db for mame2003 (via parsing the driver source code) but not fbalpha.
-
@dankcushions they also changed the expected directory for the configs - it’s now MAME 2003 (0.78) , rather than MAME 2003
-
@AndrewH yep! spotted that also. slightly annoying that things like that get changed as it breaks all overrides. i might flag that with them also.

appropriate resolution-db file
Concerning ROMS resolution in FBA I used multiple overlays made for mame2003 without any issue. That likely means FBA uses the same resolutions as mame; so no new resolution DB needed.
If you have different evidence just let me know and I'll try to build a FBA dedicated DB. -
@UDb23 i think the issue is that fbalpha has a different romset. it certainly has a bunch of games that mame 0.78 doesn't have, like cps3, and a bunch of unofficial hacks that mame doesn't seem to care about.
-
@dankcushions Right, didn't think of the wider romset.
Just need to find some spare time to and I'll create the FBA rez DB ;-) -
@dankcushions As it seems a new FBA version will come out soon, maybe it makes sense to wait and directly make the DB for that new version specific romset.

that new version specific romset.
By that statement, I take it that the FBA ROM set is expected to change again soon?
-
@mediamogul According to FBA's forum development progress posts many additional roms are supported. This includes vector games: it will be interesting to see if quality/performance is better than the recent mame2003 vector resolution enhancement.
Not sure if it just adds new roms or also some roms from previous romset need to be changed. -

It has already changed - https://retropie.org.uk/forum/topic/19741/new-fb-alpha-libretro-pre-v0-2-97-44 . The new repository has already new DAT files added - https://github.com/libretro/fbalpha/commit/4e5aeeeef7730fa4f5b17dae6f8e1b90829c9029.

At this stage to create the resolution DB specific to the DAT, considering that the DAT can&will change over time, I'll probably create some excel VBA that parses the DAT to extract the rom filenames and build the specific DB by scraping progettoemma's screen information for each rom.
When the DAT will change, just re-run the code and it will rebuild the new DB. -
@UDb23 that sounds awesome! thanks so much for your help here <3
-
@dankcushions
Had to make some changes to my previous code. It now runs correctly; here's the generated comma separated resolution file.
Based on current DAT for 2.97.44.Notes:
-
some roms cannot be found on Progettoemma's site; as far as I could checks these are hacks or particular clones.
Concerning clones I started editing the DB manually adding the original game screen info; it will take some time. -
aspect ratio values and frequency are currently dummy figures (let me know if you need the real one's)
Out of 5552 roms from the DAT, over 90% are already included in the resolution DB txt file.

@UDb23 great! thanks - i'll try and take a few hours to test it out sometime soon <3

@dankcushions Maybe its a stupid qiestion. but can I use this cfg's for games running with mame2010 and fbalpha2012?

hi! i would have thought the fbalpha configs should work with fbalpha2012 since its romset should be a subset (or close to) of the later fbalpha, but mame2010 will have many games that are not in mame2003, which i won't have configs for. however it probably has most of the common ones, so it can't hurt :)
you just have to put the mame2003 configs in the mame2010 folder, and the fbalpha configs in the fba2012 folder.
-
@dankcushions Ok, thank you reply! Another question, for example in /opt/retropie/configs/all/retroarch/config/MAME 2003 I already have config files for all the games, for example 3countb.cfg contains:
input_overlay="/opt/retropie/configs/all/retroarch/overlay/ArcadeBezels/3countb.cfg"
and that file in ArcadeBezels dir contains:
overlays = 1
overlay0_overlay = 3countb.png
overlay0_full_screen = true
overlay0_descs = 0If I overwrite that files in Mame 2003 folder, then I guess the overlay input will not work. Do I have to edit every file and copy and paste your files into these files that I already have there? Or is it another easier and faster option to do that? :)
