* Add makefile for bootrom compilation Add flag for SameBoy compilation, separate asm sources Also adds WIndows make switches Replace SameBoy PB12 encoding with old encoding GameBoy logo still not 100% Clarify Makefile, add image compilation Remove sameboy source * Remove DMG emulation of CGB games Remove unused variable. Change logo extension Remove rgbgfx option Nintendo logo correct now Explicitly define slice * Remove palette selection for CGB games * Old-style Gameboy logo * Add GBA menu option for built-in CGB rom * Restore original DMG scrolling animation * Add original CGB bios checksum verification * Add fastboot option to DMG/CGB bootroms, create new OSD submenu Also add further checksums for CGB0 bootrom and equivalent checksum C code. Grouped together all bootrom items into new submenu. Removed redundant bootroms (AGB, fastboot) * Update README and give SameBoy attribution Clean up checksum + make * Incorporate latest SameBoy boot changes Gives correct register values on boot * Update readme * Add AGB alternative boot color --------- Co-authored-by: Mark Johnson <mark.ai.johnson@pm.me>
