- CSV based configuration to replace Autoboot.bin and Au80boot.bin files.
- This can make users add a new boot mode without changes ATmega firmwares
- Refactoring with OOP aproach
- Most of source codes are shared between Z80-MBC2 and V20-MBC
- You can find pre-devined CSV files in the 'contents/SD-S220718-R240620-v1' directory.
- You can use the original SD file - SD-S220718-R240620-v1.zip - with files in the 'contents/SD-S220718-R240620-v1' directory.

- Special CSV file to switch 80-mode - S170420.CSV
- ptr Boot Offset : The address storing a boot address of second stage. This MUST be matched with 'SWITCH80.BIN'.
- ptr Boot Size : The address storing a size of sencond stage. This MUST be matched with 'SWITCH80.BIN'.
- You can determine these variable after assembling S170420.asm file with '--l S170420.lst' option.
