HP 50g in 2024, some guidance needed

[fpp]

Hi! A friend an I recently got a pair of really nice HP50g's, and we're amazed by how much it can do given it's age and it's price (around 45USD each one).

I made this thread because it's been a little bit hard to find information about different ROMs available (which one could be the best) and different programs that can improve the experience and capabilities. As of now, both calculators are on ROM 2.15, but I've read a bit about BP's 2.10-7, that it's basically 2.15, without HP's Smart stream app (I also think it's useless). I've looked at his site and also looked at hpcalc.org, and I'm not completely sure that the available download are the ROM I'm looking for. Any confirmation will be appreciated.

Also, I was wondering if there is any active (and of course, unnofficial) development on this calculator.

Thanks!
