FBA vs. MAME

Riverstorm

Edit : after my last commit, fba will search <system_dir>/fba/ before searching <system_dir>/. Also, there is no caps (same for hiscore, samples, ...), i guess it could explain why you had issues with hiscores in gyruss.

Thanks for adding <system_dir>/fba it will be nice to move the files into a system directory subfolder.

@andershp Whatever folder you have have a rom in that requires the PGM bios..it has to be present in that emulator folder along with the rom. Glad you got it sorted !

But it's not in the rom folder, it's in the BIOS folder now, and working. Are you referring to my hiscore issues? Could these be related to the bios files, and does this mean that I need to have 6 "games" in my arcade folder that's not games but really just bios files?

Has anyone gotten NBA Hangtime (nbahangt) to work? I tried the correct version of the ROMs with each mame2003, mame2003+ and fba. Both mames run teh game but without sound and fba doesn't launch.

Considering fba doesn't support this game, it seems you are lying so perhaps really try with the correct roms.

johnodon

@barbudreadmon You are correct. I downloaded the 2.97.42 FBA set from [Removed] when it was there and nbahangt.zip is included. I am now DL'ing 0.2.97.43. I DL'd the mame2003 reference set from a very common location and know it is a good set.

Regardless, the question stands. Is NBA Hangtime working in mame2003?

johnodon

Just saw this note in the mame2003 compatibility list: game plays fine yet sound is barely audible

Hoping this is corrected in mame2003+.

@johnodon No mention of ROM sharing sites, please.

grant2258

you need to go to service mode and put the volume up

@johnodon not sure why its not just nbahangtime other midway games seem to be gone from fba now dont know what the reason is

barbudreadmon

@grant2258 @johnodon those games were never in fba, we don't remove games.

grant2258

@barbudreadmon rampage used to be in fba im sure it was

barbudreadmon

@grant2258 my bad, i should have said lr-fbalpha : https://github.com/libretro/fbalpha#i-cant-launch-killer-instinct-rampage-mortal-kombat-3-and-other-midway-games-why-

grant2258

@barbudreadmon they seem to not work in the mainline anymore either didnt realise the drivers where buggy. At least i know now was wondering why they vanished

barbudreadmon

@grant2258 the author of the driver never finished the work (iirc there were various graphical issues + no sound) and has been away for a few years, i guess having this driver included in standalone releases was probably never intended.

Like I said earlier, if I ever had to do another emulation "box," I'd look into using a x86 solution where I could just use the latest MAME and be done with it and also be assured whatever other emulators used would run better than on any other platform.

I just now caught this blurb. I have been running RP on an x86 platform for months now. It never even dawned on me to run a current mame version. :-\

By the way, i'll mention it since it is something people have been asking about : next fba release will feature a lot of vector games, and the old williams hardwares (the pre-midway ones). There is no release date atm though.

Great news!
Will vector games be rendered at actual screen resolution (e.g. 1080p) ?

I don't think so, fba always renders games at original resolution. But i know there is some kind of "anti-aliasing vector drawing" technique involved. Not sure if it will need some kind of rework to the rendering part of the libretro port though (i hope not, i doubt i'll find time to work on this).

dankcushions

@barbudreadmon i guess technically vector games have 'infinite' native resolution :) since they don't rasterize there's no pixels are whatever.

yeah i can tell you it's a little tricky for the core to find the screen resolution via the libretro API. i looked into it for mame2003 but couldn't find a nice way (and the vector games crashed when i put the resolution too high anyway!)

Here's an "interesting" if not grueling read from one of the guys behind Atari vector games The Secret Life of Vector Generators.

It seems lower resolutions are a "safe" way to ignore orientation and higher resolutions become dependent on refresh rates.

The concept of resolution makes perfect sense in a raster game/monitor, but isn't directly applicable to a vector monitor/game. There are a finite number of start/end positions, but the lines between (in an analog VG) are essentially straight lines, not "pixel" representations of them.

In a Digital Vector Generator, each XY position comes from the output of a counter so the result is similar to what you would get by using a frame buffer. Since the Digital Vector Generator in Lunar Lander and Asteroids used 10-bit DACs we have a screen resolution of 1024 x 768. (We actually could use 1024 x 1024 but then the 4:3 aspect ratio of the CRT produces different X and Y scaling values.)

There's some interesting facts about vector games in the article toward the end.

In 1978 when the Digital Vector Generator was developed for Lunar Lander, memory was much too expensive for a frame buffer in a video game. The first game to use a frame buffer was several years in the future (Missile Command) and even then, it was low resolution. (It may have been 512 x 384, but I'm not sure.)

Quantum (November 1982) was not designed by Atari. It was one of the two games that came out of a legal settlement with General Computer Corporation of Cambridge, Mass. (The other game was Food Fight.) GCC got into the game business by reverse engineering the Missile Command program and coming out with a new and improved version. Unfortunately, their version still said 'Missile Command' and they got sued. (They were also accused of including some code from the original Missile Command in their ROMs.) Fortunately for them, Atari had an amazing habit of suing people, winning the lawsuit, and paying the (losing) defendants a bunch of money.

BattleZone was the first game to earn $500/week on field test. The company gave a party to commemorate this accomplishment. The game was hit of the Amusement and Music Operators Association (AMOA) show in the Fall of 1980 and was released in November 1980. (There was another game at the show that attracted very little attention at the time called Pac Man.) BattleZone sold about 25,000 units.

Red Baron was released in May 1981. It didn't do quite as well as BattleZone; it sold about 300 units. One of those units was in an airport when Wild Bill Stealey and Sid Meier played it and decided they could do better, so they went on to found Microprose.

There was also a rumor that U.S. Army Recruiters used to hang around arcades and when they saw a likely-looking candidate playing BattleZone, would go up to him and ask, "How would you like to drive a real one?"

The first 'video game' that I know of was developed in 1946. (U.S. Patent 2,455,992 Cathode-Ray Tube Amusement Device Thomas Goldsmith and Estle Mann). Although it used a sawtooth circuit it was essentially an XY game.

The first video game of the modern era (Computer Space) was invented in 1972 by Nolan Bushnell and Al Alcorn. Since the first microprocessor (Intel's 4004) was still in the process of being born, the game was a completely hardwired machine. Different operations were performed at different times according to the Counter used to produce Vertical Sync. The Motion Objects were stored in a diode matrix. The objects were created by stuffing the diodes in the appropriate holes in the PC board.

Computer Space was not very successful. The next game, Pong, was.

Tempest was the first color vector arcade game.

At some point in the early 1990s, the demand for PC graphics became hot. People wanted the games on their PCs to be as good as the ones in the arcades.
