Since there is a possibility that the Error () function will collide with libwonx.a when linking, It changed to Wonx_Error (). Added bios_exit (). sprite_set_char, sprite_get_char, palette number minus 8 Fixed bug that was not specified. font_set_monodata (), font_set_colordata (), font_get_data (), disp.c, The arguments of screen_set_char (), screen_get_char (), sprite_set_data () Changed from void * to appropriate type. Sample program and attached SpeedMac. I added a document. Version 0.3 beta - from wonx-b03.tar.gz
