Summary	03564: Many sets in cps2.c: Graphical glitches in various cps2 games test menu
Description	Example / Original report for 19xx: There is a small glitch when the coin option is selected and you alter it's value, that prevents the value of coins / credits being displayed. You can tell something is wrong by the occasional flickering or the partial yellow letters in that line. When you select another option in that menu the line gets fixed and it's displayed correctly.
Steps To Reproduce	For 19xx glitch: F2 in-game, select Configuration, select System and alter the value of the Coin option
Additional Information	There's a cps2 source change in 0.127u1 that could be causing it, but this needs confirmation: "Derived CPS2/CPS3 video timing based on measurements. These are educated guesses. The logic behind the derivations is shown in the source. [Aaron Giles]" Problems seen in: 19xx batcir cybots gigawing

No.05266 Iaspis Tester Dec 13, 2009, 15:59	I checked this further and found that it first appeared in 0.127u1 (it was ok before that). In the 'Source Changes' of the whatsnew.txt for 0.127u1 it says: "Derived CPS2/CPS3 video timing based on measurements. These are educated guesses. The logic behind the derivations is shown in the source. [Aaron Giles]" I'm not sure if this is relevant though. I hope it helps.

No.05288 Tafoid Administrator Dec 17, 2009, 19:50	Yeah, sounds completely reasonable to change it.
No.05320 Kold666 Developer Dec 27, 2009, 16:03	I am quite sure I have seen this glitch on an EURO original Dungeons and dragons. Also the glitch which happens in mame when you insert a coin happens on the pcb too... Unfortunately I have only jap versions cps2 and the glitches are not present like on mame.
No.05322 Tafoid Administrator Dec 27, 2009, 16:38	Some original (non-phoenixed) PCB tests would be great to narrow down if this is supposed to happen or not.
No.05385 Iaspis Tester Jan 4, 2010, 11:54	Entry and snap for batcir added.
No.06524 Iaspis Tester Aug 10, 2010, 09:56	As expected, still happens in 0.139. Just out of curiosity, has anyone by any chance tested an original PCB about this?
No.08167 Iaspis Tester Feb 9, 2012, 17:03	this one seems to have been fixed now
No.08171 Tafoid Administrator Feb 9, 2012, 22:17 edited on: Feb 10, 2012, 13:29	Confirmed fixed by testing a few listed games and determined fixed version.
