Beeb games running on 64k Electron with Mode 7...

Post by aerworuld » Mon Sep 01, 2014 10:25 am

Hey all!

I was originally going to post this in Adventures, but thought I would open it up to all genres...

I've recently been playing the wonderful BBC B game 'THE SAGA OF ERIC THE VIKING' by Terry Jones (Level 9) on my MRB Elk in 64k mode. The game loads nicely under Mode 7 emulation too, with all the various loading screens displaying correctly but freezes on the main game. In 64k mode without Mode 7, however, it loads and plays perfectly just without the pictures. The game won't load at all in 'Normal Elk' mode though. The version i have here is the original cassette one.

This got me thinking, what other beeb games play on the Elk with 64k/Mode 7 - i would love to hear the experiences of other forum peeps? some games will load but be a bit weird, some won't load at all...

feel free to hold back on the "just go get a beeb" comments though :lol:

Stuart ;)

Would be nice to hear about what can and cannot be used with Elk expansions and add-ons though :mrgreen:

I wonder if the BBC Micro game Orlonds Meanies (disk user disk 10) works. It is a mode 7 game.

I can't find out as I don't have an Electron.
I'm writing a game where you can change your character from a Wizard to a monkey to a cat.

Well, Imogen that!

ok, so as a comparison exercise I loaded up the DU#10 on BeebEm and also as a physical floppy in my Elk, with the Elk in 64k mode with the Jafa Mode 7 Simulator ROM running too. The results aren't a million miles apart actually, apart from the game itself... but watch the comparison video and see what you think.

I tried the Elk in Normal mode and also in Turbo mode and I also tried it all without the Mode 7 sim running, but 64 with Mode 7 comes closest.

Obviously the music on the intro screen isn't the same on the Elk but i think it handles the animation really well. well, apart from the disk going into the drive on the first screen :lol:

Presumably the game directly writes to the screen memory, but the mode 7 ROM needs programmes to use the OS calls in order for it to work.

He said not having any of the aforementioned hardware (except for Elk) or mode 7 ROM or bothered to look at the game code. Way too tired to do much of anything at the moment :(

I have found that "erik the viking" and "the hobbit" work perfectly on an elk with the mk1 mode7 adaptor as it has the all important 6845 CRTC.

I think that quite a few beeb games will run on an elk with the mk1 adaptor than they will with either the mk2 adaptor or simulator rom
