Probably you don't know:

Ristar the Shooting Star v1 GG2SMS by nextvolume 2014-05-31
- This is the first release of this patch that allows you to play Ristar, a game released in 1995 by SEGA for the Game Gear, on your Master System.
- The game works well, and is playable.
- There is garbage on the borders of the screen, but it doesn't affect gameplay.
- The Game Gear START button is mapped to Button 1 on the Master System, except during gameplay, where it is mapped to the Pause button.
- In some instances where both START and Button 1 were mapped to an action, the buttons have been inverted: one such example is the Sound Menu, where once Button 1 paused the music, and START exited the menu.
Now Pause pauses the music, and Button 1 exits the menu.
- The patch applies to a ROM image of the European and American version of the Ristar cartridge.
- In this archive other than for the IPS format patch, named `ristar_sms.ips', you can find the full source code of the injected code snippets that were used to make the patch; this means that if you are technically versed, you can improve the patch yourself.
- The Makefile is very simple and easily understood; to build the patch, simply run `make'.
The ROM image must be placed in this directory and named `ristar_orig.sms'; the patched ROM after running `make' will be named `ristar.sms'.
The Makefile assumes you are on a Unix-like operating system; if you are on Windows you can try using MSYS or Cygwin.
The assembler you will need to use is z80asm (http://www.nongnu.org/z80asm/)
inject, fixsum, nop and putstring were written by me (nextvolume), they will respectively inject a code snippet, fix the ROM checksum, insert NOP instructions in the ROM and insert a string in the ROM; do whatever you want with them, but give credit.
