Sonic Advance 2: Lower SP Ring Requirement is a patch for the Game Boy Advance version of Sonic Advance 2. It reduces the number of SP Rings needed to enter Special Stages from seven to three, making it easier for players to experience these stages while maintaining some challenge in collecting the rings. The patch includes files for all regions, allowing users to customize their game experience.
This is a simple patch for all regions of Sonic Advance 2 that lowers the SP Ring count requirement for each stage from needing all 7 SP Rings to just 3. This makes entering the Special Stage for each Zone significantly easier, while also still providing some level of challenge with locating and maintaining the SP Rings. The player is still rewarded if they obtain more than 3 thanks to the SP Ring bonus at the end of each Act. This (hopefully) provides a nice balance between challenge and collecting without giving out entry to the Special Stages right away!
Included in the zip is 3 patches for all 3 standalone releases of Sonic Advance 2. Just patch the ROM with the region you're using, and go!
Check the readme for a bit more information, and special thanks for helping with the hack.

- Huge thanks to RayCarrot again for providing an explanation for how Ghirda works and for providing GhirdaGBA, a loader for GBA ROMs.
- Sonic Retro and the developer of the original Codebreaker code to instantly reward the player with all 7 SP Rings also deserve thanks.
- Having the address for the player's SP Ring count variable made finding the check significantly easier/actually possible.
If you're interested in lowering the SP values yourself, doing a search for every instance of hex values '00 78 06 28' and changing '06' to any value lower should work, but has not been tested extensively.
Hope you enjoy!
