And in MAME 0.122u3 the title logo looks different from MetalGod's 0.134 shot (see 0.122u3 screenshot). @ MetalGod: Can you check this again!

Sorry but I cannot check older mame versions for cosmos because I don't have an older mame rom set, and current cosmos rom fails to run in mame 0.124 and below. Checking the mame 0.123 whatsnew file, I see there are plenty of changes in the 0.122 update mame versions: 0.122u7 Added all known variants of the tms5110 as proper chips. Updated dkong, cvs and scramble to use new chips. [couriersud] 0.122u6 Added VIDEO_ALWAYS_UPDATED for reliable collision detection in the CVS driver. [Zsolt Vasvari] 0.122u5 Reogranized and started to clean up the CVS driver. Added emulation of the speech CPU. Removed CVS BIOS entry. Removed unnecessary patching. [Zsolt Vasvari] 0.122u4 Rewrote the CVS system video code. [Zsolt Vasvari] 0.122u2 cvs games: according to PCBInfos speech chip is TMS5100. Changed driver to use TMS5100 and "game system operational" now sounds more natural

No.15657 MetalGod Senior Tester Oct 29, 2018, 21:05 edited on: Oct 29, 2018, 23:25	I've found out that the game title changes after playing a game, using sprites of the last enemy shown (not all of the enemies are used for this, only three). I've added the 3 possible variations. These variations are exactly the same for mame 0.202 and mame 0.125... Too bad none of them look like the flyer title.
No.15658 M.A.S.H. Senior Tester Oct 29, 2018, 22:37	@MetalGod Thanks for the informations. I added a picture from a Cosmos eBay auction (s-l1600.jpg) The colors are the same as in the MAME version. And as you said, the title logo changes constantly.
