I think there also might be some device to rip those special "cartridge"/CD from certain console, which might cost less than the actual console...(i recall this is a thing for old consoles, but i once saw one for more recent one, like PSP)
If you have time, you could probably hack a multi Disc player so it can read the output and then dump it like that...(might wanna check with a cheaper game though on the target console)
