Hi Folks,
I am new here. Decided to revive one old forgotten game gear. When found after lying for years in attic (exactly for 16 years).
The system was sort of running - but had corrupted display and off course hardly visible due to leaky caps. So what I did was I ordered new better screen from McWill here at the forum and installed everything... Had some issue that system was shutting down quickly after powered on. That revealed to be a problem with weak power supply which was not original and only 300mA. Of course I have "recapped" that GG completely.
And what happened..? Now GG runs, McWill display runs, sound sounds... but... all runs slow! I mean, the game runs very slow like GG was underclocked to half CPU speed or even less....
Also music plays half-speed, I hear ding-nothing-dong-nothing etc....
Initially I thought that it could be faulty cartridge, but today I have tested it in another GG with original screen and it runs ok... Just that damned GG runs it half-speed....
I can't really say if that problem was present before I did screen and recap, since I only powered it up for a test and screen was corrupted...
Anybody has an idea what the hell that could be??? or head of such an issue???
also that GG shows some SEGA disclaimer on start-up for a few seconds followed by SEGA logo, while the other GG doesn't show it and shows SEGA logo only... but I guess that has to do with different version or whatever...
So any suggestions ?
