171-5589D
| Games: | After Burner (アフターバーナー) |
| Game size: | 4Mbit (512KByte) |
| Board version: | I. |
| Board number: | 171-5589D |
| ROM numbers: | MPR-11272 MPR-11273 |
| Mapper used: | 315-5235 |
This Japanese SMS/Sega Mark III game cartridge board contains 315-5235 mapper chip and two custom 40-pin 16-bit ROM chips (128Kx16) in "byte mode" to make them 512KB in total, unlike it's US and European counterpart which contains only one 8-bit ROM chip (512Kx8). The ROMs have the first and second halves of the data respectively. Their CE pins are connected to CE1 and CE2 on the 315-5235 to enable them, rather than CE0.
