go49g & EMU48 on Samsung S20 problem

[Gerald H]

App works OK but can't access "Load on stack" etc.

Any suggestions?

[Eric Rechlin]

Just use Emu48. It's a superior emulator.

[Gerald H]

Thank you, Eric, for the advice.

I have tried to use Emu48 employing an .E49 file that works on my computer & on the phone in the Android app, preserving everything stored in HOME but replacing the libraries in Port 2 with Libraries 226, 227 & 229.

I would dearly like to store my Libraries in Port 2 but when I do that on the App they are deleted on saving the state.

Could you suggest some solution?

[Eric Rechlin]

I haven't had a problem with that on my Samsung Galaxy S20+. I am able to store libraries in port 2 and have them retained between sessions. (I have libraries 226, 227, 229, 258 [extable], and 993 [Jazz] there.) So I'm not sure what's going wrong for you.

I haven't tried loading an .e49 file from my PC, though -- my saved state has been exclusively on my phone.

[Gerald H]

Just to check, VERSION retuns 2.10 on my Android- is that the standard answer?

[John Keith]

Mine is version 2.6, which may not be the current version. According to the readme file, all versions since 2.0 are capable of saving the ROM with Port 2.

[Gerald H]

Thank you, John, but I mean the version of the HP ROM - I presume 1.19-6.

I have now, after repeated fiddling around & trying various assaults, to the degree that I don't know what I've actually changed, got the App to a condition where storing an altered state works & is recallable, also loading of objects on the stack works.

Meanwhile the calculator's FILES (left-shift APPS) will not open - blind management of port 2 is possible & I can view the library content via LIB (right-shift 2) - but access via FILES would be more comfortable.

[John Keith]

I can't imagine why the FILES app would not open, I've never seen that problem before. This page from hpcalc.org lists a version of ROM 2.10 made for EMU48. perhaps that would help.

Most people use EMU 48 an a 50g with ROM 2.15 but i don't think that ROM will work with the original 49g.

[Eric Rechlin]

For the record, I am also using ROM 2.10 on Emu48 on my Galaxy S20+.

The main reason for 2.15 was to add HP StreamSmart support, which is irrelevant on Android (and not supported by Emu48 anyway), so 2.10 is the way to go.

I even use ROM 2.10 on my 49G, as that's the last version that works on the Saturn-based models.

2.6 is indeed the current version of Emu48 for Android, and what I am using.
