An essential hackJets2023-03-18Version 1.2

No slowdown is noticed (even perhaps in the phases of zoom in mode 7 or use of the bomb). Work great, recommanded +++

Working good on the FXPAK Pro! And it plays great, too!tsubasaplayer162022-05-14Version 1.3

What can I say? This is a pretty good hack for anyone who are turned off by the slowdown. It's also a nice bonus to have settings and high scores saved, which is also another reason to have this hack.

And yes, this will 100% work on an FXPAK Pro (aka SD2SNES Pro) and it will work wonders on real hardware. It's a must-play if you're a fan of Contra III!

Just a reminder if you're planning on using this hack on real hardware via flash cartridges - since this hack takes advantage of the SA-1 chip, this will NOT work on the Super Everdrive (for both X5 and X6 models). Only the FXPAK Pro/SD2SNES will take advantage of that.

Great now that I got it workingimpurekind2020-06-29Version 1.3

I finally got it working - I think it was something I was doing a little wrong that caused the initial issue I had - and it's a more than welcome update and fix for the game that makes it even better than ever.

Patches of Contra IIIJoe2402019-11-17Version 1.3

You have done a great job with this patch of Contra III which repairs the slowdown Please so well could you upload the R Type III and Super Mario World patches R Type III & Super Mario World patches fix the same error that Contra III has I hope you continue with the great work you are doing creating patches to fix snes games' mistakes

A must have!Polargames2019-11-03Version 1.3

This patch really really fixes the issues of slowness, Honestly the whole game is very smooth, and quite awesome how it works. The only con to this patch is you will have to re adjust your playing because and tricks you did in the OG version will not work here, and also if you thought the OG hard was tough, well with this patch, it makes thing even more hard. So make sure you have the 30 lives cheat/patch also because you will need it. Overall this is a must to get the best out of the game. :-D

Awesome job! as it should have been!edwinmusic2019-10-28Version 1.3

Amazing job! It's something we all were waiting for years! the problem is that it does not run in the emulator for PS2 (Supernestation) the black screen appears at the beginning of the game and only keeps audio! It would be excellent to give you a solution!
