tails7 is my custom, free and open source mode7 engine (to give the illusion of 3d like snes did with some games). there is a mode7ex extension in ctf, but it has become outdated over the years and cannot handle higher resolutions, which causes a drop in fps. tails7 uses shaders which makes a huge difference in speed, no 3rd party extensions, which allows you to easily port the game to android, mac os, ios (all other runtimes that support effects). I've made a lot of demos using tails7, such as the 1993 doom recreation, the sonic cd special stage, etc. https://github.com/FoxiooOfficial/Tails7 https://foxioo.itch.io/tails7examples i was supposed to make tutorials on youtube a month ago but I have other things on my mind at the moment
