Qual o problema?

o gameboy advanced não possui FPU então operacores matematicas são muito custosas por emular ponto fluante em software, eu não sabia que com lua 5.1 era possivel alterar o number além de float32 ou double, no caso eu vou dar suporte a ambos os casos lua 5.4 com float32 ou então lua 5.1 (apenas inteiros), por padrão vai ser lua 5.1 porque isso vai ordens de grandeza em perfomance mas ainda vai ser possivel alternar usando uma flag com cmake -DLUA_MODE=
