SMS cart size detection algorithm is updated based on bank count instead of multiples of detected cart size from the header.
SMS cart size detection is only invoked if the "TMR SEGA" header is parsed for non-JP carts.
Manual selection of ROM size is now present in the SMS/GG menus to allow for manual override as detection algorithm does not work correctly for Cloud Master and Penguin Land US SMS carts.
SG-1000 Operation menu now allows for reset instead of relying on a power cycle.
Notes:
I think a better long-term solution is to implement a CRC on the first 8 KiB + database lookup for SMS/GG/SG-1000 to determine the correct ROM size (or something similar to how NES/Famicom auto mapper detection works). This is especially true as not all carts have the "TMR SEGA" header value. For now, this update allows for anyone to manually specify the ROM size regardless of the detection algorithm being invoked to address edge cases.
Testing (HW5):
I've tested manual setting of ROM size on the problematic carts:
