Conversion guide

Conversion tools:

• img_conv.exe - Image conversion tool.
• res_packer.exe - Resource packing tool.
• spt_gen.exe - Script conversion tool.

Convert image files:

• Run image_conversion.exe, click on Open Files (打开文件) and select the image files.
  • The first tab is for sprites, the second tab is for backgrounds and custom text box.
• Click Start the Conversion Process (开始转换) and the converted files will be saved in bin/.
• A background image named bg0.png will generate the following files: bg0_Info.bin, bg0_Map.bin, bg0_Pal.bin, and bg0_Tiles.bin.
• A character sprite named chara1.png will produce chara1_Pal.bin and chara1_Sprite.bin.

Create resource files (.*res) from the game files:

• Run res_packer.exe, click Open (打开) and choose the files you want to pack into a resource file:
  • For img.res, select all the charaxx.bin fils.
  • For bg.res, select all the bgxx.bin files.
  • For sound.res, select all the .raw files.
• Click Generate (生成), enter the desired name for the output file (e.g., img.res, bg.res, sound.res), and click Save.

Convert your script file:

• Open spt_gen_win.exe, click Open (打开), select your .txt script file, and then click Convert (转换).
• The file will be saved as a .spt under spt/.

You can now place the converted files along with AVGMAKERDS1.6.nds on the SD card (refer to folder structure), or run it on an emulator.

Optionally, you can create a packed ROM with the tools provided (does not work on emulator).
