any chance for crt filter? I assume something like that would be pretty unlikely for the wrapper, or am I wrong? the would make it the perfect port and give it the perfect retro feeling :D
 
For testing. I've made some more tweaks to improve performance on lower OC. And I've added the ability for it to change resolutions when docking and undocking. Screen width and height parameters are now specific to handheld and docked.

i.e.

Code: 
screen_width_handheld 1280
screen_height_handheld 720
screen_width_docked 2560
screen_height_docked 1440

I'm getting pretty stable 720p performance at 1581 MHz CPU, 614 MHz GPU, 1331 MHz RAM (which for me personally translates to 7-8 hours of gameplay on battery since the loads are relatively low).

Update: I've migrated to ini format for the config. It will automatically translate your config.txt into a config.ini. And I've now added my 3 patches into ct_nx.nro to be used at runtime.

INI: 
[config]
screen_width_handheld = 1280
screen_height_handheld = 720
screen_width_docked = 2560
screen_height_docked = 1440
language = en
game_font_path = /switch/ct/ChronoType.ttf
game_font_scale = 0.90
text_shadow_scale = 1.0
text_shadow_alpha = 200
; --- Runtime binary patches ---
cursor_fix = 1
remove_bilinear_filter = 1
remove_mobile_ui = 1

`cursor_fix`, `remove_bilinear_filter`, and `remove_mobile_ui` can be set to a value of 1, and used with the unmodified original libchrono.so. Patches are read and used at runtime, so the .so never gets modified.


I'll see if i can also get .ctp mod packs loading so we dont need to modify resources.bin.

Tested. remove_bilinear_filter is not being applied. It's easy to spot with the text

Many thanks to Nagaa and you for bringing and improving this port!

This should fix it. Thanks for the heads up.

I've also fixed the video scripts. Before at the end of the intro video it would halt on a black frame, then controller input would send keyboard input popping up the keyboard menu. Now the video progresses to after the video properly, returning you back to the main menu, and clicking a button takes you to the main menu as well.

I tested this fix and the bilinear filter is still not being removed, I made sure the config file had the remove_bilinear_filter entry set to 1, all I did was put this nro file inside the ct folder which contains the unmodified game files.

Fonts don't seem to be working either, again all I did was add the .ttf file to the ct folder. not sure if I'm missing some steps.

I can confirm its working for me. I visually see the difference with the font with remove bilinear filter on. You need to download the font file i mentioned before if you want to use the custom font (or grab another one, but ensure you are pointing it to the correct path in your config.ini). Can you post your config.ini?

The issue with the font was that I hadn't set the path as you mentioned, now it's working great:
[config]
screen_width_handheld = -1
screen_height_handheld = -1
screen_width_docked = -1
screen_height_docked = -1
language = en
gl_threaded = 1
gl_no_error = 1
game_font = 1
game_font_path = /switch/ct/ChronoType.ttf
game_font_scale = 1
game_font_xscale = 1
text_shadow = 1
text_shadow_alpha = 230
text_shadow_scale = 1
cursor_fix = 1
remove_bilinear_filter = 1
remove_mobile_ui = 1
Click to expand...

Unfortunately I still can't disable the bilinear filter, I tried setting remove_bilinear_filter to 0 and then back to 1 and manually patching libchrono.so with your python script, but neither option worked, could it be an issue with my game files?
 
Not sure... but here is bilinear on (default behavior).

Nevermind I see the difference now, it is working as intended, my issue was that the character sprites still have some kind of smoothing effect, which I though was also part of the filter, but for that I would need to patch the resources.bin file.

You gotta replace your sprites themselves. Ive set it up now to load .ctp mod packs so you don't have to patch your resources.bin manually. That way users can easily customize everything to their heart's content manually. Just cleaning it up a bit more, then I'll share this version. And you can modify ctp mod packs just by unzipping them, modifying files, then re-zipping them (.ctp is the same as .zip).

I'll think if there is a more efficient way, but this way works pretty well for now. The `.modcache` is generated when mods are present once at the start of the game, then reused for subsequent relaunches of the game based upon the mods that are present. It takes a little time to generate the cache on startup, but after its generated loading is just as fast as before.

Mods go in `/switch/ct/mods/` in `.ctp` format.
