mame2003-plus: hundreds of new games, improved input, features, new bugs - now with runahead support

@REK607 Ok the fix is in for Gunbird 2, update to the latest version of MAME2003+ and try playing it again and lemmie know if it crashes

arcadez2003

Three more games now playable in this core........

Opa Opa (Rev A Unprotected) only this version will work opaopan.zip

I've always wanted to play the arcade version of Opa Opa, however it was one of a number of Sega games that we could not emulate in the ole cores for two reasons,
firstly code to decrypt the protected rom was not compatible and secondally the video code would be incorrect anyway, so even though finally an unprotected
version of this game popped up it was no good as the only way to get it to work i thought was update to a special HAZEMD Sega E driver from MAME113 which
again would not compile in a million years in MAME2003+

Well as luck would have it i remembered FBN Dev's used a combination of the same ole Sega System E driver as we have and simply spliced in some Sega VDP
video code from later MAME builds so that Opa Opa and Fantasy Zone 2 would work, so i contacted dink about this and with his help and advice around which
parts of that video code i would require i ported it across to MAME2003+ and finally im able to play this game and so can you if you want via the latest build.

I just added the following two to fill up the Sega System E driver with the games we can support here and to make the code changes i did go a little further
every game now works barring Fantasy Zone 2 which would require the aforementioned decryption code.

Slap Shooter

Tetris (Sega System E Version)

Big thanks to dink of the FBN dev team for help and advice regarding the video changes needed for Opa Opa and Slap Shooter to display correctly in this core

Is it possible to get Killer Instinct running full speed on MAME2003+ on a Pi 4? With threaded video on, and the 0.78 CHD and rom KI runs pretty decent as is.

Anything is possible personally i have no interest in looking into speeding up the Killer Instinct games once again i got nowhere last time.

Plus im just about to fire up Xenoblade Chronicles on my Nintendo Switch so i'll be off the radar for a while :)

What is the big roadblock? No need to answer right away - enjoy your time off and I appreciate your efforts!

We need this apparently and it's above my level to port something like this across to MAME2003+, that is the roadblock more or less and until someone raises
a significant bounty that might tempt someone with more skill than me to attempt to port it the road will remain blocked :)

@arcadez2003 I wonder if this could be used in someway - https://github.com/pcercuei/lightrec

That one wouldn't help at all actually, it's x86_64 only.
Supposing someone would be interested in this, is old MAME code compatible with GPLv2 code ? If so there are several arm mips3 drc that might be reusable (mupen64, pcsx-rearmed, ...).

RA is GPL and its api code is integrated into old mame . I dont see why it should be an issue if its already changed its license to gpl at runtime technically.

You don't "change license at runtime", same non-sense as saying a program X would be under the same license as windows because it run on windows
libretro api license is not gpl and limited to libretro.h only : https://github.com/libretro/libretro-common/blob/master/include/libretro.h#L4

The header file just point to code it retroarch . Id love to waste time in licensing with you but been there done that. No need to do it again. No one has the money to get a lawyer so people will sell boxes and people will pretend they arent breaking licensing. The world goes on. If someone uses i doubt anyone will blink or find a loophole

Then stop the harassment about this, i'm sick of reading this shit, what you are saying here is also akin to saying any program running on linux becomes GPL, since any linux program will use glibc which is GPL. NON-SENSE. Period.

grant2258

I just dont happen to agree with you and you started the licensing nonsense above. You done it on the yabuse thread too and im pretty sick of the mods letting you swear all the time on here. There is no harassment a simple fact ra mixes licenses.

@grant2258 you've been warned before, I don't want to police any topic that @barbudreadmon posts just because you're trying to get into an argument with them.

@barbudreadmon please, try to use a less colorful language in the future.

How is it the same ? The bizhawk git repository indeed mix incompatible code together, that's not the case for a libretro core, nothing at https://github.com/libretro/FBNeo is under GPL license afaik.

You saying you didn't harass me about that while you even told the retroleaks guy to contact me about it on reddit is ridiculous, as always.

@mitu please unban him, or it's going to escalate even more, he already holds me responsible for his ban at libretro, i'll just try to ignore his taunts in the future

REK607

@arcadez2003it worked! I could finish the game with no problem, only it's a bit slower when you use the bomb and the screen is full of enemy bullets being converted to candy (I'm using the young witch). Brilliant as always, thank you :-)

Oh, I didn't know that it needs tools. I thought lr-mame2003-plus will generate it automatically via its tab menu entry "GENERATE XML DAT" from its internal drivers or so. What kind of tools are needed? (just curious)

Ok then no problem thanks for clearing that up, certainly i have no interest in this so it'll be upto someone else to pick up the baton
