No.07937 Kold666 Developer Dec 4, 2011, 13:29	I already sent everything to tafoid to be added in mame, for your information: 6502 = 18mhz/24 (yes it's 750khz) z80= 18mhz/6 2x AY8910 = 18mhz/12

No.07960 hap Developer Dec 10, 2011, 19:01	It's a different issue but yeah, too much green in it, and not just the background color. Could you add a photo of attract mode? And a close up of PCB color proms resistors? I saw a pcb pic on your old site, with lots of resistors on one side of the pcb, but the photo sharpness is not high.

No.07976 Kold666 Developer Dec 16, 2011, 08:59 edited on: Dec 16, 2011, 08:59	The original pcb is very similar to the bootleg, there are so many resistors that it doesn't make sense to take a picture without tracing the pcb. On the board there are three proms 1kbit (256x4) named R, G, B. Pin 12 is O1 Pin 11 is O2 Pin 10 is O3 Pin 9 is O4 I will try to trace to which resistor value are these four lines of the proms connected

No.22773 hap Developer Jan 6, 2025, 01:17	The small picture on the top-right shows blue: https://www.arcade-museum.com/Videogame/pinbo Screenshots at the bottom are emulator screenshots, not counting the bottom-left one. https://flyers.arcade-museum.com/videogames/show/4036 The flyer shows a blue background, very hard to see since the picture is so dark, definitely visible on the 2 close-ups at the left (the ones with Bonus) If I google around, I also see photos of ones with a black background. Maybe different hw revision?
