Undo part of r2230 (Frogger related):
"also fixes that the frog disappears for player 2 if moved backwards. This will position him on x=242. All games in this driver now have the sprites in cocktail/player 2 now offset by 2"
It made sprite offsets in cocktail mode wrong in every game. The Frogger glitch must be due to something else, not this.
sx=base3 -> sx=base3+1: As documented in video/galaxold.c, this is evident in many games: scramble, turtles, anteater, jumpbug, spdcoin, ..
----
also cleaned up video/galaxian.c source a bit and renamed anteater clones (anteatg/anteatgb to anteaterg/anteateruk). I couldn't be bothered to add anteater colorsplit to galaxold.c, so the clones aren't fixed
Added new support for Ruleta RCI.
New games added or promoted from NOT_WORKING status
---------------------------------------------------
Ruleta RCI (6-players, Spanish) [Roberto Fresca, Rob Ragon]
Added M48T37 variant to timekpr.c. Fixed some bugs that caused
registers to be initialized to 0xff and caused odd behavior.
Updated to modern device timers.
Converted vegas to use M48T37 instead of its own implementation.
conversion efforts: [Atari Ace]
* taito_f3 is disentangled from a number of other drivers by using
an AM_SHARE tag instead of a common variable.
* Several drivers are made into explicit subclasses of other drivers:
8080bw from mw8080bw, missb2 from bublbobl, quasar from cvs, taito_x
from seta.
* arcadecl is separated from rampart by duplicating the bitmap
rendering code.
* jaleco decryption code is moved to jalcrpt.c.
* cischeat is separated from megasys1 by duplicating some video code.
* mcr3 is partly separated from mcr.
* machine/midwunit.c is split into wunit and xunit files with some
code duplication.
* midtunit gfx_rom variables are made distinct from midyunit
variables, making midyunit independent of midtunit.
* contants in namconb1 are duplicated/renamed in namcofl.
* namcos2 uses of namcos21 are eliminated by introducing
namcos2_kickstart.
* toypop is separated from mappy by duplicating some video code.
memory consumption when iterating through all drivers like -romident
does.
Also moved softlist scanning into the main loop so that machine_configs
are only constructed once.
=====================
Catch (prototype) [Siftware, hap]
-------
not working flag is because of the broken sound
also, should it be a clone of avalnche?
