Hey Felipe first of all TY for asking in kind and polite way I will be honored to share my games with you and the rest of the Speccy community.....My original games for ZX Spectrum that you can use are :Dark Transit,Dark Transit II,Astro Phobos
The rest of the games/mods on my itch channel are not my own games it's just mods of some popular games that I change or separate tap files for easier loading also add something else like loading pictures fast loading etc....
