I recently got a ROM for Tantei Jinguuji Saburou - Kiken na Futari and it's one of those Famicom Disk System games that came out on 2 disks. I heard that sometimes people merge the two ROM files into one for convenience and I want to know if the ROM file I have is a merged one. I read somewhere that the 2 individual halves of the game are 128KB and the file I have is 256KB so does that mean it's a merged ROM file?
