tation those two games didn't work correctly unless 4-way mode is set to off, which makes sense since you can't move at a diagonal with it on. I would never set direction/diagonals as a default global

@Riverstorm no problems ive posted workable solution theory to this for the new 4 way so it can support these games but we will need a list of games and agreement its the best way to do it first its in the github thread

Here's what I could find for 45 degree rotated games. Their might be more to add though.

Congo Bongo
Inferno
Jack Rabbit (8-way stick but uses only diagonals for gameplay)
TYLZ
Q-Bert
Q-Bert Qubes

Public service announcement about romsets

Based on support requests I've handled from the libretro Discord server, there are at least two different bootleg mame2003-plus romset collections now floating around.

It may be that one of these collections is good and reliable but also maybe not. In the meantime I've also moved our romset rebuilding instructions to the official libretro docs: https://docs.libretro.com/library/mame2003_plus/#building-romsets-for-mame-2003-plus

Rebuilding your romsets is the only way to know for sure that you have a good set!

PUBLIC SERVICE ANNOUNCEMENT ABOUT VECTORS

nayslayer has contributed a patch to mame2003 that should fix its longstanding video quality issues rendering vector games. Once the patch is fully working, it'll get ported to mame2003-plus as well. @caver01 I can't resist the urge to tag you, although no worries if you don't have time to take a look right now. :)

If anyone is interested in testing this improved vector quality, rebuild mame2003 from source (not mame2003-plus) and give it a whirl with Tempest, Star Wars, or your own favorite vector game. Edit: You will need to change your mame2003 vector-related core options, as the old un-enabled core options for vectors will still be place even after you build from source.

markwkidd

The new vector patch is now in mame2003-plus as well -- rebuild mame2003-plus from source for new adventures! I only had a tantalizingly small amount of time to play with the options but things are looking very snazzy!

Here's Tempest at 2x resolution, antialias, and a beam width of 3 (click to see it at full size or you may get aliasing re-introduced by your browser):

caver01

@markwkidd thanks! As a contributor I have been copied on all of the bounty messaging too. I have to admit the I have only loosely followed the 2003-plus conversation but that interests me too.

I am looking forward to trying the vector games this weekend. I am so curious how they might compare to advmame.

I don't get this picture if I use your settings. The vectors just get wider and more blurry, but the resolution remains very low. tvservice -s shows the current resolution to be 1600x1200. It's the same with mame2003 and mame2003-plus. What am I doing wrong?

Asteroids with blurry vectors

dankcushions

@Clyde did you rebuild both from source?

Clyde

@dankcushions Yes, both. mame2003 yesterday and mame2003-plus today.

Argh, never mind. I had to quit and restart the cores to change the resolution. A restart from RA's Quick Menu wasn't enough.

dankcushions

@Clyde haha, ok cool! it even says to restart in the option text ;)

Clyde

@dankcushions Yes, but there is a Restart entry in the Quick menu. I thought the text meant that one.

I am loving the new 2003 plus; so far, I am happy to report that the ROMs I have tried so far are all functioning much better than when I was mucking around with the original 2003. Having sound work in DK is really wonderful.
One thing I noticed is that the copyright warning that pops-up seems to be on by default. When I went into the retroarch-core-options.cfg file, I noticed this:

mame2003-plus-skip_disclaimer = "enabled"

mame2003-plus_skip_disclaimer = "disabled"

The second occurs several lines down, but additionally, the latter use an underscore after the word "plus" while the former uses a dash after plus. Now I am not sure which is correct. The file actually has the first few with a dash and the latter with an underscore (see below for a paste from the file)

mame2003-plus-dcs-speedhack = "enabled"
mame2003-plus-samples = "enabled"
mame2003-plus-skip_disclaimer = "enabled"
mame2003-plus_brightness = "1.0"
mame2003-plus_dcs_speedhack = "enabled"
mame2003-plus_dialsharexy = "disabled"
mame2003-plus_display_setup = "disabled"
mame2003-plus_enable_backdrop = "disabled"
mame2003-plus_four_way_emulation = "original"
.
.
.

Now I am not sure which is correct. I assume it is the dash, but the odd thing was that the file in my case showed it as enabled in the first case and disabled in the latter, but it seemed to be reading the latter. I just set all instances to enabled, but have not checked to see what works just yet. Anyone know which is correct or why the cfg file is variable?

Maybe the text should read "Resart core"... that seems like a good idea.

markwkidd

@zenobiaflex If it wouldn't cause you any particular issues, I would suggest deleting all of the mame2003-plus options in your retroarch-core-options.cfg and run the core again.

Earlier in its evolution there was a slight name change involving that dash/underscore character and for whatever reason you have some entries with the old name scheme still in your file.

When you clear them all you should only get the valid ones repopulated automatically.

That text in the core options now reads Restart core. Thanks.

Anyone tried the new implementation of vectors WITH a retroarch overlay ?
Does it impact performance ?

nayslayer who authored the patch said they tested it with RetroArch overlays with no trouble. I don't think they were using an rpi but they were being sensitive to low power in all regards on the implementation

@markwkidd thanks.
If I find time will do some testing tomorrow, both on performance and on best overlay size @1080p.

Now I am not sure which is correct

The underscore is correct. The same for the warnings which I had to add manually due to it not saving correctly in RGUI. Samples are a dash.

@markwkidd
Updated from source lr-mame2003 (Retropie 4.4.2 on Pi3 b+, no overclock) and started testing new Vector support.
In Tempest for any multiplier over 2x (tried 3x and 4x) the game screen gets corrupted, meaning lines (vectors) are missing.
See picture below:

Tried with and without antialiasing. Restarted rom multiple times, still same issue.
Also tried restart from inside the RGUI menu.
