Silver Night's Crusaders is a fan-made, Castlevania-based free game for PC and Android platforms, developed by True Role Dreams (Crimsondeath) from Spain using OpenBOR game engine. It isn't a metroidvania, instead it's more of a side-scrolling arcade action game, which splits into several stages rather than a massive sprawling map.

Castlevania: Simon's Destiny is a free (non-profit), fan-made small game developed independently by Batandy with GZDoom engine, based on Konami's Castlevania franchise. This game was originally announced and released in 2017. It is completely standalone, not an MOD (so doesn't require DOOM2.wad), only GZDoom is required to play!

This is the original edition of Streets of Rage: XXX (another remake edition of SoR series) with 8 playable characters, made by an 80's fan player from China. Later it was modified many times by more fan players (later I will release one of its enhanced edition).

Beats of Rage (BoR for short) is a doujin/homebrew/remake game made by Senile Team in OpenBOR long time ago, which is inspired from the classic video game Streets of Rage (SoR) series of SEGA and SNK Playmore's King of Fighters (KoF) series.

Super Mary Cat (the original Japanese name: しょぼんのアクション, AKA: Open Syobon Action) is a kuso version of the classic Super Mario game, when gaming there are too many challenges waiting for you, this let us complain about the author's tricks, meanwhile, we can't help feeling so much interest. Just because of this, Super Mary Cat has become a must-play Super Mario remake for its fans.
