200mhz Gp32 Experiment


i remember saitek made an alkaline recharger, which, as long the alkaline wern't completely discharged charged your alks back up, they sold out in like a day.
 
I heard that the NiMH batteries have problems with "memory" does anyone notice this? The best is LiIon but I haven't seen those available in this size.
Yep, NiMH rechargables suffer from the so-called memory effect.
This means: If you recharge them before they are empty, they lose capacity.
LiIon don't have this problem. You can load them whenever you want.

So, if you use NiMH, be sure to get a charge device (that thing that recharges the batteries, don't know what it's called in English ;)) that decharges first and then recharges.
No they dont. The memory effect is in NiCD batteries not NiMH, which explains why NiMH cost more.
You cant lower the battery life of a nimh by not discharging it buit you can shorten its life by overcharging.
My reccomendation is to get a charger that stops charging when the batteries are full

Mine hit 220, I ran for a minute then rebooted...dont wanna kill it.

What would be the real consecuence of running @200~220 as a regular speed, other than battery life (ac adapter where I play, so its cool)
 
Well it seems pretty stable around 200mhz, so I will see about upgrading to this speed and if it can be done reliably.

You should be able to mod any emu to any speed, just replace its 133mhz settings with the settings for 200mhz.

OK for 200MHz but I would also try 220MHz...can someone give the settings plz?

see you :lol:
I will definitely get this mod.

But I thjink going to 220mhz would be a little extreme.
(on the other hand everything would run at this speed - I have a 266mhz pentium 2 that run's lots of things very well - and that is with resource hogging Win98)

:blink:

You still have the ram problem, which would be solved if you did the ram upgrade to the gp, which not everyone (like me) is willing to do.....
 
You can HEXedit SNES9x (not OpenSNES9x, at least, afaik) fairly easily to a different clockspeed. Look around Google. [/quote]
There is no need to edit opensnes9x at a hex level, since at the name suggests it is open source.

RAM is runninf at half speed of the CPU and is theorically limited to 133MHz so that makes 266MHz max for the CPU

You dont need to upgrade RAM except if for eg. you are interrested in GPlinux...

Can Mr.Mirko add to his tester up to 266MHz feature please?
Or just a Hign clockspeed tester:
166,176,188,200,210,220,230,240,250,266...something like that...Just to see if the GP can fry...
(I gonna test it ASAP and report here :D)

see you :lol:

:blink: You are insane!!!

I would keep below the "theoretical" limits if you don't want something to go wrong.

No you don't.
And besides lots of people would upgrade their RAM if Aquafish made a firmware which supports more RAM, and If someone else with more experience did the mod for them.
And if developers could just add it into their code by default (I heard it wasn't difficult).
Somebody else said that the extra Ram wouldn't eat up that much battery (but I'm not entirely sure...)

I dont think insane is the right word...crazyshould be better :p
in fact it is just to test and I heard that if the freq is set too high then the GP just reboot without damage...I hope this is true...

BTW: What do I need to compile Osnes9x?

see you :lol:

So great :)
After how many hours of test did you determinate that your upgrade is "stable" (concerning the 166 Mhz upgraded units you're currently selling) ????
Hummm is it possible for you to sell some GP32 BLU certified to run at some higher speed than 166 Mhz ??? (with of course a slighty increase of price too ^^)
