Re: Graphic glitch in Space Demon by Fortrek
05/31/12 01:03 AM


On the Space Demon boardsets from fortrek the Ess Sound board layout has extra components and an extra 74LS74 chip than the Nintendo Space firebird Ess boardset. I have verified both sets of Mame roms from an original Space Demon boardset made by Fortrek and space firebird roms set including the bi polar proms and all the roms verify the same in winromident with the same checksums.I believe it is the additional components on the ESS board that is causing the blue background issue as the video board works in conjunction with the ESS board. I have taken some pictures of the areas on an original fortek space demon boardset that are different than the space firebird.Having schematics would help for the original space demon ess boardset. One other difference too is a 10k resistor is replace by a 20k resistor and is printed on the board itself.
