Is RG34XX SP a good option for non GBA games?

Hello, I am planning to buy a rg34xx sp after tinkering with a clone r36s for some time. I wanted a clamshell console because of mobility and carrying in pocket but its 3:2 screen Is giving me second doubts. Because i want to play PS1, N64, NDS, PSP games and some other postmaster ports. I really don't know what to do and need some advices from someone.
