Lots of file have been udpate, see commits

It doesn't seems to work right now but it's a necessary step for investigating and try to fix games like Chuchu Rocket freeze at launch

NullDC4Wii - Alpha 0.24

⚙️ Improvements

Game Presets

NullDC4Wii now come with a custom game_preset file !

Edit game_presets.cfg in sd:/data

This aim to automatically put the best setting (or YOUR best setting) to the game, depending of its name

Graphism

gxRend.cpp => fixed Ryo's missing head in Shenmue (#24)

Please update compatibility Guide

https://wiibrew.org/wiki/NullDC4Wii/Compatibility

Presets

For now you can do your own presets (or modifiy the existing one) but I'm aiming to reorder game_preset.cfg in alphabetical order in the next release

👨‍💻 CACHE

CACHE_NORMAL has been duplicated to CACHE_QUALITY

CACHE_QUALITY is now CACHE_EXTRA (only accessible with code and not preset or menu for now)

CACHE_NORMAL has an hash map optimisation (should have better FPS than CACHE_QUALITY)

NullDC4Wii - Alpha 0.22

⚙️ Improvements

• 2 players mode ! For now, you need to activate this in the main menu before launching game.
• Loading on USB has been tested : it's confirmed that it's working !

👨‍💻Developpers

Log (re-)activated on real wii

Initialy there was a log file at main.cpp (to sd:/ndclog.txt)
The thing is that is disabled printf() from displaying on screen
Since the basic menu uses printf(), I had to put it in comment (since Alpha0.03 probably)

now the logging to file (at root : sd:/ndclog.txt) has been moved to gxrend.cpp (initrend)

this will help to identify thing that works on dolphin, but not on wii

CACHE improvement -better graphism !

new cache presets :
CACHE_VERY_FAST ( original algorythm)
CACHE_FAST (still flickering)
CACHE_NORMAL (ok perfect)
CACHE_QUALITY (ok-perfect - debug only)

Downfall :

• New CACHE mode (FAST/NORMAL/QUALITY) has less FPS

👨‍💻Developpers

fps_boost has been removed, it was unecessary for now

NullDC4Wii - Alpha 0.19

4BPP and 8BPP pipeline improved

CI4 (FAST) and CI8 (FAST) are the default to ensure max compatiblity

I aim to do a per-game profile config file, this would be the bebt solution. RG565 usually work thus.

Help bug #27

Please test & report improvement & regression

👨‍💻Developpers

4BPP and 8BPP also have a GREY mode option, this could help debugging
