Summary	06513: gba: Many previously working gba sl_roms now freeze
Description	It seems that MAME 0.182 may have broken 100s (perhaps 1/3, or more) of previously working gba sl_roms. Problem remains unresolved in 0.183 - Win32 or 64. All was well, in 0.181. The freeze occurs immediately after the initial 'Game Boy' screen.
Steps To Reproduce	A couple of run strings, to illustrate problem modes, and show what I'm doing: white screen, most quiet (this one), but a few with static: K:\Games\Mame\mame64.exe -cheat -nodrc -artpath "K:\Downloads\MAME EXTRAs\artwork" -cheatpath "K:\Downloads\MAME EXTRAs" -hashpath "K:\Games\Mame\hash" -rompath "K:\Downloads\MAME ROMs;K:\Downloads\MAME Software List ROMs" -samplepath "K:\Downloads\MAME EXTRAs\samples" -sound dsound -video opengl -output console -snapname "soft-lists/gba/spongbmvu" gba -cart gba:spongbmvu black screen, static: K:\Games\Mame\mame64.exe -cheat -nodrc -artpath "K:\Downloads\MAME EXTRAs\artwork" -cheatpath "K:\Downloads\MAME EXTRAs" -hashpath "K:\Games\Mame\hash" -rompath "K:\Downloads\MAME ROMs;K:\Downloads\MAME Software List ROMs" -samplepath "K:\Downloads\MAME EXTRAs\samples" -sound dsound -video opengl -output console -snapname "soft-lists/gba/spongbmvup" gba -cart gba:spongbmvup As examples - some (not all) of the now freezing sl_roms (from between Sonic and first few Super Marios): ..., sonicgen, spongblcu, spongbbv, spongbmvu, spongbmvup, spyroice, spyroatr, spyroflm, spyroicej, spyrornga, spyrorng, swep3, swep3u, swndroid, swndroidu, swtrilgy, swtrilgyu, steelemp, strawrc, strawd, sfa3, sfa3u, sfa3j, srs, srsu, srsj, suprbpop, sdsumos, superhrn, smad, sma2, sma2u, sma3u, ... You should be able to jump into the list, about anywhere, and within trying 2-3 games, find one that freezes.
Additional Information	The problem seems to reside within MAME, not gba.cpp or the sl_roms, as these freezes do not occur when running MAME 0.181 against 0.183 ROMs, 0.183 gba SL_ROMs, and 0.183 EXTRAs.
