   Olivier Galibert for all the assistance and information he's provided
   R.Belmont for working on the SH2 timers so sound worked
   Nicola Salmoria for hooking up the Roz and improving the dirty tile handling
   Paul Priest for a lot of things
   Stephh for spotting what was wrong with Puzz Loop's inputs
*/

/*
ToDo:
   Priorities
   Transparency effects (each pen has a transparent flag, there are seperate r,g,b alpha values to be used for these pens)
   Idle skipping on other games + bios ..
   Fix gaps between zoomed sprites (See Gals Panic 4 continue screen and timer)
   Fix broken games

Alpha pens:
   galpanis uses them to white in/out the bg's during attract? Solid white atm.

Priorities:
   Puzzloop appears to use the priorities, the other games might use alpha effects to disable a layer instead ..
     *they don't appear to use alpha, so how should it work, senknow intro, galpanis attract,  cyvern level 4?

Ram-Based Tiles:
   The front layer in galpanic games
   The kaneko logo in galpanis
   The Bios

Sprite Zoom:
   Used all over the place in the Gals Panic games, check the bit in galpani4 attract where if you hammer the button the ballon expands until it bursts.
   Puzz Loop main logo

Roz:
   Should be used on galpani4 bg's, but for some reason incxx,incxy,incyx,incyy are always 1,0,0,1 resp. Maybe a timer problem, input problem or core problem. Who knows?
      Update, rand() was returning a 15-bit number under mingw. Top bit seemed to determine whether it rotated or not.
   To zoom the skull in the senknow attract mode
   To zoom the girl at the end of a level in galpanis
   To zoom the kaneko logo in galpanis

Linescroll:
   Puzzloop intro, the screen covered in 'puzz loop' of varying sizes, the little ones go left and the big ones right.
   Puzzloop title screen uses it just to scroll the bg up.
   Also used behind the hi-score table on puzzloop...
   Galpani4/galpanis use it for 2P mode on both bg A and bg B.

R,G,B Brightness:
   The Electro Design games have this set darker than 0xff for sprites and bg's anyway.
   Galpanis uses it to dim the bg's in attract on the stats screens for the characters (bg's hidden by white pen atm).
Lots of games use them to fade, haven't seen r,g,b used independantly yet but you never know.

etc.etc.

gutsn Crash Reason
the routine at 401d8c8 calls 40249e0 with r14 as a parameter, which points where the return pr on the stack is
param is 60ffbc0, pr is at 60ffbcc, but 40249e0 writes more than 12 bytes
Gutsn now works in 0.69, timing/sh2 fixes??
