I downloaded the ROM and it's now sitting in /ROMs/HP49G+/rom.49g+, but I don't know how to load it. I tried 'Load Object' but it gives me an error.

Can someone please post instructions on how to load a new ROM?

Thanks!

I figured it out. Since I had already set it up as an HP48G, you have to go to settings and uncheck "Auto Load On Start". Then it will ask you to pick a ROM and set it up as a new calculator.

Thanks Alexis Lorca for creating such a cool and useful app for HP48/50 fans.

[Edit]
After successfully loading the HP49/50 ROM and using it over the last couple of days, I decided to switch back to the HP48 ROM for the following 2 reasons:

1. There is a noticeable input lag with the HP49/50 ROM. If you type too fast, or try to navigate a long menu quickly the calculator will stop and beep at you. As someone who is used to enter data quickly, this became an issue for me.

2. The shift key indicators are not visible on the display. So if you press left-shift, right-shift, or alpha, there's no quick way to see if the key was pressed or not. This also led to many input errors.

The HP48 ROM is very quick and stable and doesn't suffer from the above issues, so I recommend using it instead.

Cheers

Regarding observation no 2 you can fix that by using a different skin.
I have also noticed observation no 1 and unfortunately have no solution to it.
