BeebEm for RG350 (Retro Handheld)

Post by j6wbs »

Hiya,
I have put up an initial release of BeebEm (Acorn BBC Micro emulator) for the RG350 (Retro Handheld), and will appreciate feedback.

https://github.com/jeremyrayner/beebem- ... beebem.opk

Image

A big thanks to Bob Fossil for the RS97 version upon which this is based, and for his direct help in getting started with this little project.


To install, put beebem.opk into your APPS folder on the RG350, it should then appear in your Emulators section.

Running BeebEm at least once will create the ~/.beebem/roms/ folder if not already present
You will then need to locate and put System ROMs (aka BIOS) with exactly these names into ~/.beebem/roms
'acorn_dnfs' - Acorn DNFS 1.2 (chip ID# 201666)
'os12' - Base operating system for BBC Model B (v1.2)
'basic' - BBC Basic Programming Language (v2)

Sources: https://github.com/jeremyrayner/beebem-rg350/

Note:
I've made it save per-game keyboard mappings and settings to ~/.beebem/kbd/ folder,
and you can save state of emulator to the ~/.beebem/saves/ folder too

There is a bit more detail About BeebEm for the RG350 over on the RG350 forum here https://boards.dingoonity.org/retro-gam ... for-rg350/

I’ll be keen to hear from any stardot members, if you get this running, I think the RG350 can be had for about £60-£80 on Amazon (ymmv) and it is great fun to have the old BBC games with you as you travel.

Cheers

Fans of Chinglish should check out the pictures in this listing on Amazon.
Smooth without fever, stronger operation.
And the obvious fake reviews.
There is no hot problem.
This is probably not the Amazon Marketplace vendor to buy it from :shock:
There is so much wonder in the universe; why should you want to imagine that there is more?

absolutely, buyer beware and all that, unfortunately Acorn don’t make these so you have to be cautious these days.
For those that are interested, I purchased mine from amazon.co.uk from Anbernic Seller Inc for £83.99, I have no affiliation or interest in them, I just think it is a nice device and the particular unit I received has worked well so far. I have replaced the SD cards and flashed the firmware to the latest stable (1.5.1), however the out of box experience was pretty good. Steve Benway has a nice video about the device here... https://youtu.be/9Kp-kf7pCLQ which is what tempted me in the first place.

Cheers

Nice work there, I just received a RG350M and was pleased to see your port.

It works really well, I had a good bash at Life of Repton last night!

Are there any config options to push this into a BBC Master Mode? Prince of Persia calls! :wink:

I'm having real problems getting this to work, can anyone help?

1. I've got the 3 ROMs and renamed them as basic, os12 and acorn_dnfs but when I try to run a game I keep getting the error message "Read ROM Error - Cannot open ROM image File 'basic'! - Ive tried the basic ROM from different places but I keep getting the same error.

2. Game ROM format - when I download any game ROMs they are zipped. Should they go in the ROM directory zipped or unzipped? When unzipped i get a mixture of TextEdit files, Notepad files and plain text files. Which do I use?

3. What file extension should the game ROMs be?

Any help would be much appreciated

Attached are the ROMS I used, Linux is case sensitive, so that may have caught you out?
You also need to copy them to the TF1 card /usr/local/home/.beebem/roms using the DinguxCmdr

On point 2, they should be unzipped SSD/DSD/or UEF (tape) format

doubtful, but the RG350 version is a port of the RS97 version.

Hi, my first post here so please be gentle with me!!

I've got an RG-350, Pocket Go 2 and an LDK Game all with the BeebEm emulator installed. Pretty much all the games I've got work fine with the exception of one. Which is Tempest, I just can't map the dpad or analogue stick to get it to work. When I select Joysick it just goes round the edges super fast.

Has anyone managed to get Tempest to run on the RG-350? If so how did you map the keys?

Thank you in advance.

Phil
