[ASM & Hex] Safe temporary variables

[Rendan]

Hello, I'm writing a program in ASM and I need many variables for this program exclusively. I know that variables from 0x8000 to 0x8007 are safe, I'm pretty sure of that but are there more variables ? Can I use variable 0x8008 ? How many variables (adresses) can I use in an ASM program, for a temporary usage ?

if you're not looking to interact with a script, then there's no reason to use a variable at all when you could just use free ram space

I am working with a script. And I'm looking for free ram space, but I don't know where to write. I need to know where it is safe to write data. Variable = ram space, it's basically the same thing, it's memory.

Space from 0x0203F400 up to 0x0203FE00 should be free to use. Source: this video

Also, the usable temporary variables are from 0x8000 to 0x800B and from 0x800D to 0x800F. Also, here is a ram map of Firered if it helps.
