_________How To Enter Challange Game Mode________________________________________________
- Before inserting Main Game Disk to DF0 put the Challenge Disk into one of your DF1 to DF3
- If data format on Challenge Disk is correct, than the game will change the white screen toward to red one while loading. Challenge Mode is on from now until you reset Amiga.
- You can prepare your own challenge with your personal score record to beat and share this challange with your friends :)
- To prepare Challenge Disk follow exactly "Challenge disk data format" or better edit data on the basis of existing Challenge Disk
- Yoy can use any text editor to edit Challenge Disk data. Each of line can be ended both with <CR><LF> (Windows standard) or just <LF> (Linux standard). Ironically the Commodore standard (single <CR>) is not supported ;)
- You can write those data to regular floppy disk starting from sector 0
- If you write data to *.adf disc its size should be 880kB - i.e. 901120 (0xDC000) bytes long. If you change some text in existing disk without override mode better to allign disk size.
