Can't play SNES in Treo 650

[carytakeuchi]

I try to use LJP to play SNES in my Treo 650.
But it can't.
The msg is out of memory although I already use UDMH.
When use UDMH, LJP was show my machine have 18MB memory can use.
But it still can't play.......
I can play Mega Drive game in my Treo without switch on UDMH, why can't play SNES?
Any suggestion for me?

I'm having the same problem. I know I at least go all the basics right, because my NES games are working. I just can't get the SNES ones to work.

Maybe the SNES module is bigger than 4 MB?

[Tinnus]

No, it's around 2.5 IIRC... try to hard reset (defragment memory). Fiddle with UDMh settings.

It's weird because the Genesis module is even bigger than SNES... but I think SNES uses more run-time memory.

BTW: Is there any list of all Palm OS 5.x PDAs and the amount of free dynamic memory and the largest block? Could be helpful for everyone. Maybe one should write a tool, which tries to get this infos.

[gerorne]

Ok, I feel stupid. I just didn't activate the trial version of UDMH. It works now. But my SNES games are kinda slow. Anway to get them to speed up? Do just free more and more RAM?

If I free up ROM is that more important than freeing up RAM?

[Tinnus]

Freeing memory doesn't help speed at all. The only ways to speed up are use an overclocking tool, be sure there's nothing working on the background (keyboard drivers?), use frameskipping, turn sound off.

[gerorne]

Wait... I thought that's what UMDH does? I just must not understand some very basic thing about what memory LJP is using.

But what about freeing up ROM. (It's not against the rules here to talk about that is it?) I can remove some programs that I put in ROM. Would that help?

[mikelx215]

ROM is read only memory that stays in your palm after a hard reset, it contains data such as the Palm OS opperating system and basic applications such as notepad, memopad, datebook... Freeing it up won't help you in terms of speed and it'll make your palm unusable.

ROMs are games that run on non-PC systems that can be played on a PC (Or other device that the game was not intended to run on) using an emulator. LJP is an emulator that allows your palm to run various types of ROMS on your palm. Downloading licenced ROMs for free is considered illegal, so you should never post links to pages containing ROMs.

These two terms are similar so i can see why you may be confused, as for your speed problem, I would reccomend using an overclocking program.

[gerorne]

Thanks for the reply. That much I knew already.

And actually shadowmite has developed a program that can remove certain programs from the ROM of the 650 while still having it remain stable, like the World Clock and built in calculator and tutuorial that I never use, which allowed me to store some programs like zlauncher and butler into that freed up space. (But of course there are warnings everywhere in the instructions and on his site about being careful, if not your phone may be destroyed.)

But I guess I just don't understand what UDMH does then. It works. That much is evident... I just don't know how.

But ok... I may try an overclocking program. And maybe I'll just overclock it just a tad and stick to RPG's and puzzle games. I'd like to keep up my battery life. I guess I don't have to be greedy and play Street Fighter and Donkey Kong Country on my phone.

There are 2 areas of RAM, storage and dymanic. Programs need dynamic most of the time. UDMH takes storage (usually larger) and turns it into dynamic so programs can use more run-time memory if needed (ie: for SNES).

It doesn't make LJP get faster.

[gthing]

I had the same problem until I set UDMH to leave some storage ram (about 1mb or so I think). So if you have a total of 18megs, tell UDMH to show 16 or 17 and leave the rest for storage. Should work okay then.

Also, sometimes you can click past the memory errors and use the reset snes button in the on screen menu. Then it will suddenly work without complaint.
