|Tester||M.A.S.H.||View Status||Public||Platform||MAME (Self-compiled)|
|Version||0.135u4||Fixed in Version||0.185||Build||Normal|
|Summary||03619: nsub: Missing background blue color fade effect|
** NOTE: inverted colors were fixed in 0137u4 **
The 'Known issues' of N-Sub (Sega 1980) in the vicdual.c driver says:
"Colors are wrong in N-Sub. It uses a different resistor ladder."
This is not correct, the color prom region is simply inverted.
Change in ROM_START( nsub ) line 2424 from:
ROM_REGION( 0x0020, "proms", 0 )
ROM_REGION( 0x0020, "proms", ROMREGION_INVERT )
If you now compare both attached images from the TAFA flyer and the
new MAME snapshot (Level 2), you can see that all colors are correct.
Only the *Blue Sky* color fade effect is missing. This fade effect
looks like the same in Mariner (1981) or Radar Scope (1980).

|It's no doubt closer and seems like a correct fix. Again, though, console ports of a game are not a good basis for comparison - flyers are probably the most accurate sort of having actual working video from a game.|

|The schematics have no trace of a circuit similar to e.g. radarscope. However, the manual list "11 MR-1024 TV Mask" together with some fluorescent light assembly. ==> This is something for the colleagues from the artwork department.|

Fixed by SailorSat in MAME 0.184/0.185:
- 0.185: SailorSat added video\vicdual-97269pb.cpp for N-Sub.
- 0.184: SailorSat simulate the gradient in N-Sub. Figured out how the starfield and gradient get enabled on VIC Dual hardware.
