Sonic The Hedgehog Improvement Hacks Comparison 

what's interesting about the gba improvement that it's not a rom hack, but rather a proof-of-concept. and it's made by stealth, one of the people who worked on sonic mania

the original GBA game being official is so crazy to me still. at best it looks like a mediocre bootleg also i love NES improvement ngl, and the original bootleg of that was pretty charming in it's own right, also very impressive for a console that was outdated and very limited when the bootleg came (1994)

personally the sms version has its own little charming style, doesnt really need improvement

Sonic the Hedgehog NES Upgrade - Spin-dash - 7 Emerald Chaos - Super Sonic Excellent Port and Levels Upgrade

Wow, I never thought that the community is able to improve such games a lot. Nice job uploading this! 😊

The best improvement in the video is (warning; don't read if you don't want to ruin the sonic 1 title screen for yourself forever) (...) The logo being centered instead of slightly to the left.

WOW!!!! SEGA SHOULD'VE PUT THE IMPROVED SONIC THE HEDGEHOG FOR THE GENESIS INTO SONIC ORIGINS!!!! EVEN EGGMAN TALKS TOO!?!? OH THEY DEFINITELY NEED TO SWITCH OUT THE ORIGINAL SONIC THE HEDGEHOG WITH THE GENESIS IMPROVEMENT!!!!!!!!!!!!!!!!!!!!

The Improve one looks so so awesome too
