Press CTRL+A in your file browser and drag and drop the files onto TI-Connect CE/TILP. Make sure all the files are in archive memory, not RAM, and you should be good to go!

There are 29 appvar files alongside the program, labeled Sonic2.8xv and Bank(04-31).8xv. They contain all the game's code and data, so the game will automatically return to TI-OS if any of them aren't found. Make sure to double-check.

Thanks for the help, but for some reason it keeps saying "One or more files was invalid and could not be sent to the calculator". Idk, if it's my calculator or if I'm doing something wrong.

It's been about six months since Version 1.00 of Sonic 2 CE came out, and I'm happy to announce that Version 1.10 is coming out in about two weeks as a part of the 2024 Sonic Hacking Contest!

This version improves the framerate by adding frameskip, allowing the game to usually reach the same level of speed as 1.00's fast build.



On top of that, Green Hills Act 3 has been overhauled, removing the trial-and-error gameplay that was in all previous versions of 8-bit Sonic 2. Beating the game on this version allows you to see a Sonic Mania-style results screen, showing the time it took for you to beat each level and which Chaos Emeralds you collected in your run.



Finally, a French translation has been added, with zone names mostly being pulled from the French manuals for the original game.



While it won't be available at the Contest, you will still be able to download it here day and date with the English SHC build.

Until then, see you later!

I was wondering if you could fix the level select screen, everytime i try to select a level it skips through like 5 at a time.

That's actually the first thing I fixed in 1.10. I just forgot to mention it.

Congratulations, you won an honourable mention in the "technical" category from the 2024 Sonic Hacking Contest!

S2CE for the win/mention!

Also, v1.10 is now downloadable on GitHub. There's now the option of downloading a semi-complete French translation that wasn't at SHC2024, too!

I know I say it a lot, but thanks for all the support!
