Title: Sega Astro City problem with some games Post by: Demetris74 on June 16, 2014, 06:11:05 am Hi Guys
I have a Sega astro city and bought some games recently, It seems that old games have scrambled graphics or thats not the case? Golden axe, pit fighter tetris. other games i like bad dudes, Solomons key tekken, work fine. Is it something to do with the Monitor sync? the monitor of the astro city is 15/24khz its a Nanao. Is it something i can work out from the monitor chassis? i tryed with the front panel horizontal/ vertical e.t.c but no success it shows like scrambled graphics http://i785.photobucket.com/albums/yy134/info318/WP_20140616_004_zps40cf6f0f.jpg Appreciate your help Title: Re: Sega Astro City problem with some games Post by: John's Arcade on June 16, 2014, 08:17:58 am Does the monitor chassis have a jumper to select either 15k or 24k? I think it does. Are you changing that setting to match the PCB?

What i have read is that some Bootleg games have this problem with sync on astro city dont know if thats a fact rgrds |
