From this sentence, I have deduced that a 8 megabytes ROM can be created with SGDK, and use it in a MD cartridge without problems.Stef wrote: ↑Mon Oct 26, 2015 9:55 amActually you can use rom up to 8 MB (even 10 MB with a bit of extra hardware) without bank switching but if you do it, you are not anymore compatible with Sega CD nor 32X addon. Also you need a specific emulator to handle large rom like that.
Bank switch is the safe and official way to go for rom above 4 MB but then you need to switch bank when you access data > 4MB and you need to write specific code to handle these cases (SGDK do not give tools for that right now).
Is it really true (I am always mind restricted to 4 MB ) ?
This is a new world of possibilities!
