Does the Cpu and Lcd Tweaking util have any known issues on the 1.1.0 firmware? It starts ok and i can make changes, but when i try to display the test picture I just get a black screen, and when i hit Select to save the changes it just locks up the gp2x. It works well too as i can see the screen flicker disappearing as i cycle through the lcd settings, i just cant save anything.
 
Mine went through a stage last night when it locked up whenever I tried to adjust LCD settings, Did it 3-4 times in a row (Only using settings I've used loads of times before)

Tried the same thing this morning and had no issues...

Who knows.
 
I read a post (sorry, can't remeber from whom) that said these settings work nicely:

Timing prescaler: 2
LCD-Clockgenerator = UPLL

I have the latest FW and these work for me, every time no matter what I set the CPU speed to (I can run stable @ 266mhz).
 
hmm, just does the same thing using those settings. Its odd, I cant get the NeoGeoCD emulator going either, it just goes to a white rom select screen where it only shows one rom, an i have to tilt the screen at an angle to see the rest of the roms on the list, an whatever rom i select, nothing happens. Weird. So far the only thing thats worked flawlessly (prog wise) is good ol DrMD. :) (albeit i havent tried much else yet ;) )
 
with firmware 1.01 i couldn't get 280mhz to work the gp hanged when i tried that, but now with 1.10 it works just fine...
And i think everything runs a bit smoother even without clocking now with 1.10 just tried BOR though but that worked much smoother...
I haven't either got my NeoGeo to work but as you say DrMD works realy great...

Do you have the test picture in the root directory?
It needs to be there :)

The latest version is 1.2 ... get it here.

1.2 is a little bit more stable than the 1.1c and has a fancy testscreen. Put the test.bmp (there's one in the zip-file, but you can paint your own picture :) ) in the root.directory of your SD-Card, otherwise it doesn't work.

I posted it before ... for those people with a freezing gp2x:

1. use version 1.2
2. if you don't change the CPU-clock, quit with start ... this should deal with the freezes.


NOTE: V1.1c = ~25kb, V1.2 = ~480kb. If you want to put the tool in your profile-file (autoset at boot), you better use the 1.1c, because it loads faster.

EDIT: Please read the README.TXT ... there are some minor changes in V1.2 i don't mentioned here, because i'm to lazy :D.

And ... btw .. merry christmas
 
great a new version got to try right now....
oooh crap charging batteries....
gotta go and get some better mine sucks....!!!

Just downloaded and the info at the archive doesn't meantion anything about version 1.2 and the date is kind of old.
If you upload a new file wont the date update?? if so i thing you should fix this so that it will show the updated picture..
Well can be me that missed the update.. just a bit curious...
 
i have 3 pixels which look weird in the main menu and on the test picture, changing the prescaler to 8 gets rid of them and fixes it but the screen is then shaking slightly, any ideas?


to be specific the three dots are in the bottom right corner of the screen like so "..." they show up as white pixels in the menu and on the test image

I posted the new version in the specific NEWS-Tread.
Because is uploaded the new version again and again (some issues with the readme :D) the indo-text was set back to the previous version :-/. Now it should be right.


@Paradox: I have the weird pixels too :D they don't bother me.

i also got 3 strange pixels on the bottom/right of the test picture, sometimes they are more , sometimes they are kinda shaking, depending the prescaler, but i haven't seen them anywhere else than in the test image :huh:

With the old firmwares (1.0 & 1.01) it was recommended not to go higher than 266MHZ. Is it now safer to go further (like you did at 280MHZ) with the new firmware (1.10)?

no, not safer, the standard CPU frequency is not firmware related, everything over 266mhz is, was, and will be overcklocking !

i don't think it's risky anyway, but not more nor less dangerous than with the previous firmwares ;)
 
I got my gp2x! WOO HOO!

I booted it up.. firstly there was this white screen, colour bars.. then nothing..

Second time colour bars (i get colour bars almost all the time now, with a white background) then the gp2x black screen kicks in.. it loads up then im on the explorer!

The screen is a little hazy at times, small wavy lines (not of colour, but more like interference like a bad signal on the tv, the old analog tv that is)

After installing drmd, the menu for drmd was flickering all over the place, less at the top, more at the bottom!

Also, the pixels were not as sharp as the gp32 because of this HAZE type thing.

SO, i proceeded with the firmware update, the firmware updater.. i was too scared to try another way.

I did the test, it was great, worked fine. Then did the proper thing, i now have a new boot screen! And also it boots slightly faster, and the red attery light is off during the rest of my gp2x experience! yay!

And now also the menu in drmd is fine :)

With the firmware updater, i followed the instructions carefully, 1) did the test 2) did the proper version with the kernel of firmware updater. 3) ... it says to use patch00123 or whatever .gpu ... i put that on there after downloading it from gp2x.com but when i boot it and go to game, explorer i see nothing except drmd a couple of folders. but then i realised now that maybe i should boot it from apps and not GAME.. oh well..

I then proceeded to use the lcd tweaker. Coz the hazy screen in still there (GEE THANKS gamepark holdings!!) . it works a treat, i set it to FPLL, 266mhz cpu and -4 lcd tweak. i press select to save and now the screen is sharp like gp32's and drmd is SMOOOOOOOTH! its so wonderful!

I use uniross 2500mah chargables, been at it for 4 hours and the battery meter is on medium, its really cool! Was playing drmd for 2 hours last nite on full 266mhz! battery still going :)

Well, i do have this problem though, im so happy with the gp2x (although it recognised im my pc, i cannot SEE it as a drive, even though windows said its installed and working properly... damn you BILL!)

Well, ok the tweaker...
I do the same settings as before, press select (i wish you could save this instead of having to tweak it everytime u turn it on!) I run drmd..
Now, this is the strange part, every game i load up, i have to map the controls TWICE! No matter how many times i save settings and even save settings for each game, whenever i go to select rom, select the rom and play either right dont work, up dont work. left and right is switched... its all strange!
I go to configure controls and then remap the contros, i go back to the game, it works for a second and stops again, like not going left or up etc) so i go back to configure and do it again. then when i return to the game i get no control problems!

Its strange, anyone else had this problem?
If i dont do the lcd tweak etc drmd works fine. STRANGE!


Also, is there any way to make the tweaks you make PERMANENT?

Thanks ;)
