- Added DSiWare detection - Start INI Work for DSiWare. PUB and PRV save creation not added yet. - Only modify VRAM if running on a flashcart (resolved Giana Sisters DS regression) - Remove Card DMA configuration to align with nds-bootstrap removing it as a configurable value - Show a message to the user if using akmenu-next for the first time
