|
|
Greetings one and all.
I have recently procured a GD FS7 form Tototek and all appears to be working well.
I do however have a question for you seasoned veterans:
I occasionally experience slowdown where none would be present using an original cart. Good examples of this are the Super Starwars games (occasional) and the R-Type games (notable slowdown on Super R-Type).
Slight slowdown has been spotted on Super Mario World. Surely that game shouldn't cause slowdown!?
My FS7 has 2x 64m RAM (red, Tototek type) and I am using it with an original (not mini) US SNES.
All contacts are clean and all ROM's were prepared properly with Ucon64.
Is the slowdown normal or is there something wrong?
RAM perhaps?
I would be grateful if anyone could offer any info.
Thanks.
Sorry for my poor English. |

Nothing is wrong if it's working but I'm not sure why you're experiencing that. Super Star Wars is a fastrom game (the first one) so maybe your RAM is too slow? I remember Super Star Wars having some slowdown when playing from cartridge though. |

Thanks for the reply, kyuusaku.
I am led to believe (by various internet sources) that only the early backup devices were unable to support fastrom games properly (hence the slowrom fix available in Ucon64).
Could it be that Tototek's RAM is slower than it should be?
I have already dismantled the device and thoroughly cleaned it, I also added a brand new Samsung floppy drive.
All works fine and the selftest does not show any errors.
I am, however, using the standard, 'straight through' adaptor, not the DSP one. Could this have any effect?
Thanks again, mate. |

Not in the least. Fastrom games have 120ns ROM, and while your RAM is probably 70ns, the logic causes further delays but should still be under 120ns. I remember that with 80ns RAM on a Magicom, it couldn't play Super Star Wars without a horrible amount of slowdown (once cracked) but a new EPLD was released that somehow made it work reasonably. If you had 60 or 70ns, it would play reasonably and wouldn't crash. The same thing goes for Aladdin. You can check how fast your RAM is and if it's 70ns or under I don't know what to tell you, I guess you'll have to live with it ;) |

Ok, mate.
Thanks for the help.
I'm sure I can live with it.
How do I check the speed of my RAM though? |

You can check the RAM by looking at the chip, the suffix -60 or -6 denotes 60ns. |

Indeed, yes!
After all the work I put into that beast, you're lucky it isn't 800x600 |

Ahh, I see.
I shall do that next time I decide to wipe the RAM and change games.
Many thanks. |
