GDEMU 5.20.5 Clone Bug

[ferrycorsten]

Hello, I've tested the GDEMU 5.20.5 clone with Skies of Arcadia and it freezes in the intro where the grey creature pops up, in exactly the same place 5.15B does. I thought 5.20.5 was supposed to fix it? So maybe it is just a fake stamp and it's really just 5.15B?

this does not happen on my 5.20.5

mention if yours is a clone or not

It's likely not your problem, but you don't have the "read_limit" parameter defined in your GDEMU.ini file, do you? If so, either remove it, or set it to "read_limit = -1".

thanks, in my ini it has:
read_limit = 0

i'll try what you said

yes that worked, no freezing now, thank you!
do you know any other tests i could do which have been fixed since 5.15B?
thanks again

Wow, I'm so glad! Please see an explanation of all INI configuration parameters here: https://gdemu.wordpress.com/operation/gdemu-operation/

For a clone GDEMU, I suggest the following configuration:

Code: Select all

open_time = 1000
detect_time = 1000
reset_goto = 1
image_tests = 0
high_speed = 0

Regarding other fixes for v5.20.x, there's the "Resident Evil: Code Veronica" item bug, but that takes a bit of playing in order to test. There's also a patched version of the game now that mitigates the bug for pre-v5.20.x GDEMU firmware.

Otherwise, both "Nakoruru: The Gift She Gave Me" and "Sakura Wars: Columns 2" exhibit mild texture flickering issues on pre-v5.20.x firmware, both of which were fixed after I spoke with Deunan (GDEMU creator) about it. The easiest of the two to test is "Nakoruru". Start a new game, progress through maybe the first 5 minutes. When character textures change on screen (i.e., current person you're speaking to), if you never notice any type of weird flicker, you're good!

For "Sakura", you have to play one of the non-story modes (like "Shonen Red"), beat or lose a level, then watch as the character texture scrolls in from the side of the screen along with a win/lose message. Before v5.20.x, this texture would stutter a bit as it slid on screen.

THANKS a lot for your help, would you recommend these settings for both 5.20.5 & 5.15B clones?

I don't believe the image_tests parameter does anything before FW v5.20.0.

Regarding the open_time and detect_time parameters, it seems that different clones behave differently, and oftentimes these values need tweaking depending on the model. See these two posts for some other input on the subject.

The easiest way to test how these parameters are affecting the disc-swap button on the GDEMU is by using D2. Load up disc 1, then select "Opening Movie" from the title screen. It'll ask you to insert disc 3. Assuming all four discs are sequentially placed on your SD card, you simply press the GDEMU's button twice (pausing three or four seconds in between each press) to cycle up to disc 3. If successful, the movie will play.

yep, before FW v5.20.0, image_tests = 0 is default value

yes well the default settings worked perfect for loading games on 5.15B but most games wouldn't boot with these settings on 5.20.5, I had to change settings and add lines to the ini for games to even boot, it would just fall to the bios menu
