Here is a trainer Ive made for The Binding of Isaac it should work on all versions of the game but if doesn't tell me so i can update.
---32 and 64 bit versions available---
Insert - Show Trainer
F1 – Infinite HP
F2 – Infinite Bombs
F3 – Infinite Coins
F4 – Infinite Keys
*If menu doesn't show sometimes and just the trainer process is working you you'll have to manually end the process when done sorry
