The FPS indicator does not work with double buffering. Follow-up on this issue is ongoing.

v0.6 2024/10/23

Implemented position cycling by using START + Analog left/right
Fixed PSP Go battery life indicator
- The PSP Go battery circuit is different from older models. It doesn't contain a controller to have the exact current state of the battery capacity
- High, Medium and Low values replaced the percentage approach for this model
- Implemented isPSPGo utility function, checking for Tachyon version 0x00720000 and 0x00810000

v0.5 2024/06/07

Implemented Globals structure containing all shared project variables.
The declaration of Globals fields is done in their respective threads.
Defined macros to improve readability.
Improved getFPS function by removing overhead.
Implemented getCpuUsage and printCpuIndicators.
- getCpuUsage implementation thanks to darko79.

v0.4 2024/06/06

Improved getFps function by changing sceKernelGetSystemTime with sceKernelGetSystemTimeLow (reduced overhead).
Implemented key combo (L + R + Start) to show/hide the HUD.
The plugin logic was separated into three different threads.
- missyhud_worker_thread is in charge of system calls and computations.
- missyhud_gui_thread is in charge of drawing the HUD.
- missyhud_control_thread is in charge of reading user input.

v0.3 2024/06/04

Implemented printFps to get the actual frame-rate by hooking sceDisplaySetFrameBuf to increment fps_counter.
- hook.c implementation thanks to Alexander "Raphael" Berl.
- getFps implementation thanks to darko79.

v0.2 2024/06/04

scePowerGetBatteryLifePercent crash the PSP when waking up from standby. Replaced it by manually calculating the remaining capacity percentage.
