-    TODO (updated as for April 2014):
+	TODO:
-    - all Model 2B games: FIFO comms looks way wrong, and 3d is mostly missing/incomplete. Games also tends to stalls at some point, culprit might be when i960 tries
+	- z-sort, focal distance, color gamma and Mip Mapping still needs to be properly sorted in the renderer;
-      to use a burst type opcode read;
+	- FIFO needs to be properly emulated in the various CPU cores (we currently rely on some workarounds);
-    - Inputs needs device-ification and clean-ups;
+	- sound comms still needs some work (sometimes m68k doesn't get some commands or play them with a delay);
-    - daytona: runs at half speed in gameplay;
+	- 2C games needs TGPx4 emulation;
-    - desert: several 3d bugs, presumably down to FIFO;
+	- clean-ups;
-    - dynamcop: stalls at stage select screen;
+
+	TODO (per-game issues)
+	- daytona: crashes when coining it up with master network active
+	           culprit is a wrong command parameter in geo_parse texture data opcode;
+	- daytona: car glasses doesn't get loaded during gameplay;
+	- doa, doaa: corrupted sound, eventually becomes silent;
+	- dynamcopc: corrupts palette for 2d (most likely unrelated with the lack of DSP);
+	- fvipers, schamp: rasterizer has issues displaying some characters @see video/model2.cpp
     - fvipers: enables timers, but then irq register is empty, hence it crashes with an "interrupt halt" at POST (regression);
     - lastbrnx: uses external DMA port 0 for uploading SHARC program, hook-up might not be 100% right;
-    - lastbrnx: uses a shitload of unsupported SHARC opcodes (compute_fmul_avg, shift operation 0x11, ALU operation 0x89 (compute_favg));
+	- lastbrnx: has wrong graphics, uses several SHARC opcodes that needs to be double checked 
-    - lastbrnx: eventually crashes in attract mode, geo_parse_nn_s() is the culprit apparently;
+	            (compute_fmul_avg, shift operation 0x11, ALU operation 0x89 (compute_favg));
-    - manxtt: missing 3d;
+	- manxtt: no escape from "active motion slider" tutorial (needs analog inputs), 
-    - motoraid: stalls after course select;
+	          bypass it by entering then exiting service mode;
-    - pltkidsa: after few secs of gameplay, background 3d disappears and everything reports a collision against the player;
+    - manxtt: no bikes are visible (not a z-sort issue!);
-    - skytargt: MAME hardlocks after disclaimer screen;
+	- sgt24h: first turn in easy reverse course has ugly rendered mountain in background;
-    - srallyc: opponent cars flickers like wild;
+	- skytargt: really slow during gameplay;
-    - vcop: lightgun input is offsetted;
+    - srallyc: some 3d elements doesn't show up properly (trees models, last hill in course 1 is often black colored);
-    - vcop: sound dies at enter initial screen (i.e. after played the game once);
+    - vcop: sound dies at enter initial screen (i.e. after played the game once) (untested);
-    - vcop: tilemap priority bug at stage select screen;
+    - vcop: lightgun input is offsetted (needs to be calibrated in service mode);
-    - vf2: stalls after disclaimer screen;
+	- vcop: missing 3d bug at stage select screen (priority?);
-    - vstriker: countdown in team select goes way too fast ...
+	- vstriker: stadium ads have terrible colors (they uses the wrong color table, @see video/model2rd.hxx)
-    - vstriker: ... meanwhile gameplay is way too slow!?
-    - zeroguna: stalls after some seconds of gameplay;
-
-    OK (controls may be wrong/missing/incomplete)

-    ---------
-    overrev: sound CPU crashes.
-    vstriker: shows some attract mode, then hangs
-    manxtt: no escape from "active motion slider" tutorial (needs analog inputs), bypass it by entering then exiting service mode
-    manxtt: crashes after the title screen, the TGP is the cause
-    pltkids/pltkidsa: crashes after some time of gameplay.
-    rchase2: fails drive bd i/o check
-
-    TODO
-    ----
-    Controls are pretty basic right now
-    Some games (sgt24h, indy500) hangs at random places, presumably due to a regression with the SHARC fifo comms
-    Sound doesn't work properly in all games
-    System 24 tilemaps need more advanced linescroll support (see fvipers, daytona)
-    2C needs DSP still
