No, no, they're all new and mine (never been a group), there are thousands of games untranslated, I don't think I can do all of them xD
Fortunately, there is a "new wave ()" of spanish translators, Jackic, Semco, Max1323..., which I have contact with, and they are doing great efforts to bring even more games out (and bigger ones!)
I agree with that, I translate the games because the translating process is fun and I want to complete as many as I can, most of the time playing them is the worst part, but I test the games by myself (with cheats!).
Maybe a "crappy game" I translate brings back memories for people that had them and they can relive that and the game will be even better for them.
"I don't think I can do all of them"... but I think you will try haha
You are right, the new wave of Spanish translators do a great job, and I have even helped out Spanish translators sometimes to do font hacks, etc to up their quality. Some of the recent Spanish translations are impressive.
