Summary	06410: cpc6128: Failed to show correctly new graphic modes!
Description	Imperial Mahjong - http://www.pouet.net/prod.php?which=68307 The game features new graphic modes: EGX (Extended GraphX): displays 16 colors in 320200 instead of 4. EGX2: displays 4 colors in 640200 instead of 2. The Mess/Mame CPC128 driver failed to show correctly the new graphics modes!
Steps To Reproduce	Insert the disc and type run"config" on first start. Once the game is configured, type run"mahjong". (Note: It needs any CPC fitted with 128k !)
Additional Information	The game is tested to work fine on following emulators: CapriceForever Beta v0.29 (2016.09.10) - works fine! JavaCPC Desktop v2.9.5b (2016.07.12) - works fine with small glitches on the screen top when moving the arrow! (at least on my PC) WinAPE 2.0b1 (2015.11.26) - works fine! WinCPC 0.9.27 build 4185 (2010.08.15) - works fine! Unfortunately, other CPC emulators failed!

Btw. For the MESS Forum topic, the "S&KOH" demo might be a nice test case too! A lot emus have some problem with it, even WinAPE, but the new CapriceForever Beta v0.29 seems fine! (IMHO, possibly the best CPC emus today)
