I made a Genesis port of the Thunder Force II intro sequence from the Sharp X68000 version. The binary has been tested on a real machine. On a PAL system, graphics should be displayed at 320x240 pixels resolution, it will also work on NTSC systems (320x228 pixels). For now the overlay text is in Japanese only. If you can translate it to English, let me know

The ROM is attached. You can find the source and more information on
GitHub . The binary can be build with SGDK 1.65, but it is recommended to use the latest master.
Merry Christmas!
