Introduction

This repository hosts all of resources, which include SDL2 and ALSA source code, needed for supported devices. The NDS emulator I used is DraStic emulator (close-source) which extracted from RetroPie package and the ELF binary is in ARM32 format, not AArch64. The DraStic version is v2.5.0.4 and sha1 is ae9c215bdea88359cbcb3c259ce0d60a1f59986c. In this porting, I focus on SDL2 and ALSA libraries and heavily customized on DraStic emulator. Therefore, there are some hooking points used in this emulator. To ensure it works properly, please use the correct DraStic emulator as mentioned before. It is welcome to file any suggestion or issue on this GitHub but I must say that I cannot make sure whether it can be fixed or included in the release build. Since the SDL2 library used in this repository is heavily customized, therefore, it is not recommended for generic use-case on any supported device.

Terminology

Term	Description
Keypad Mode	This is the default mode and it is so-called gamepad mode.
Stylus, Touch, Touch Pen or Pen Mode	It is touch mode. In this mode, the touch pen shows on either top or bottom screen. DPAD is used to move touch pen and A button acts touch point.
DraStic Menu	The default DraStic menu.
Customized Menu	It is a special menu to customize all of settings for my porting. This menu is not DraStic menu. So, I called the customized menu.
Normal Resolution	This is the default display resolution on DraStic emulator and the resolution is 256x192 pixels.
High Resolution	Turn on "Change Options -> High-resolution 3D" in DraStic menu and then the display resolution will be changed to 512x384 pixels. In this mode, only single screen is rendered.
Wallpaper, Background Image or Theme	It is background image.

Q & A

Q1: How to add a new language ?

Step 1: add the new language file in "resources/translate" folder, ex: resources/translate/jp
Step 2: replace font.ttf file which supports your target language in "resources/font" folder
Step 3: change the language in the customized menu

Q2: How to customize the DraStic menu ?

The background and cursor images are put in "resources/menu" folder.
The color can be set in "resources/settings.json" file as the following:
    "menu_c0":"0xffffff"    Text color when select
    "menu_c1":"0x000000"    Text color when un-select
    "menu_c2":"0x289a35"    Highlight color

Q3: How to apply the overlay image ?

Place image in "resources/overlay" folder.
Go to the customized menu and then change the "Overlay" setting to apply it.
Please note that the background image will be disabled when the "Overlay" setting is enabled.

Q4: How to change the initial CPU clock ?

Change "./cpuclock 1500" to what you want. (1500 = 1500MHz = 1.5GHz)  
For Miyoo Mini, the maximum CPU clock should be <= 1550MHz (experimental value)  
For Miyoo Mini Plus, the maximum CPU clock should be <= 1850MHz (experimental value)

Q5: How to change the maximum/minimum CPU clock ?

Change the "maxcpu"/"minpcu" value in "resources/settings.json" file.

Q6: How to add a new wallpaper (so-called background image or theme) ?

All wallpapers are put in "resources/bg_640" and "resources/bg_752" folders by the screen resolution.

Q7: How to add a new image for pen ?

All of pen images are placed in "resources/pen" folder.
The touch point is set by the suffix file name.
For example, if the file name is 1_lt.png, it means the touch point is at left-top (_lt).
Here are the supported positions:
    xxx_lb.png: left-bottom
    xxx_lt.png: left-top
    xxx_rb.png: right-bottom
    xxx_rt.png: right-top

Q8: How to enable high resolution 3D mode ?

Turn on "Hight-resolution 3D" settings in DraStic menu.
The display resolution will be changed from 256x192 to 512x384 pixels.

Q9: Workaround (if DraStic emulator always shows white or black screen)

Go to DraStic menu and then select "Restart Game".
