Manic Miner (Electron)

Building on the great BBC Micro version by TobyLobster: viewtopic.php?f=74&t=22323

Current Elk version now with correct colours, music, and code/data garbage in screen memory hidden:

Awesome !!! You've just made a lot of people, very happy !

[TobyLobster]

This is looking great with all the on screen 'garbage' removed! It looks like it's playing at a good speed so far, and the music plays nicely too.

[0xC0DE]

Thanks DamoJay and TobyLobster. I wouldn't even have started on this without the great improvements done by TobyLobster

Well done, Kelvin . . . as usual

Thanks Dave!

Great job guys ..... just wondered why there never was an Electron version available ...
Manic Miner was very popular those days.

I wondered that myself! But soon there will be MM on Atom, Beeb and Elk

Sound effects are in as well. 78 bytes free. No more OSBYTE and OSWORD. Next up: final tweaking.

very cool

very cool

Thanks!

Fantastic! And it looks like it's even in mode 1? It's pretty rare you get an Electron game in one of the 80-byte modes.

Thanks Thomas! It's MODE 1, though half of the frame time is spent in MODE 4 for obvious reasons

I just released Manic Miner 2021 v0.06b for the Acorn Electron.

Again, many thanks to TobyLobster for making this possible

Amazing work! For me this will be one of the greatest releases for the Electron, my first computer was actually the Oric Atmos and Manic Miner was my favourite game, was always disappointed that I couldn't get it on the Acorn Electron. This looks amazing! Seems to be moving much quicker than the original Software Projects release on BBC!

Thanks! We only had to wait 35 years for it
The speed is acceptable due to the enhancements TobyLobster made to the BBC Micro version and the speed hacks I added to the Electron version.

Another great game made available by 0xC0DE. Great job Kelvin

I tried to load this game over WiDFS but I get a "Bad program" error after the intro text is displayed. There is data loaded ("garbage" on the screen) but the Manic Miner graphical screen does not appear. What memory areas does this game use? I think there is a memory collision in WiDFS with the game....

The UEF file is running fine with WiCFS ( load it with *WGET -U HTTP://ACORNELECTRON.NL/UEFARCHIVE/0XCO ... CMINER.UEF and then *WICFS and CHAIN "" ).

[TobyLobster]

This is great! It looks like a lot of work was needed to get this in shape for the Electron, but the result is excellent. Good job 0xC0DE!

[0xC0DE]

Thanks Roland! Yes, this is using most of memory, except &0200-&0380 and &00d0-&00ff.
The loader executes on the bottom of the stack at &0100.
The main binary is loaded from &1F00 until far into screen memory.
And then one part is relocated to &0380 and another part after the visible screen (at the top of screen memory).
I still have to test on MMFS to see if it works.

Thanks to you Toby! I did have to change quite a few things but it was a perfect side project for me. And as a result one of the games I remember fondly from the Spectrum is now finally available on the Electron

The loader executes on the bottom of the stack at &0100.

Well, that explains a lot. WiDFS also uses part of the stack and the string buffer at &A00....

This illustrates the transformation of the initial test and the final game

Yay, it's all excellent stuff !

Will take a 'few hours off work' tomorrow to try it on my Electron - vanilla Release 2 (not even a Plus 1 at the moment), PlayUEF your tape image straight into the tape port !

Marvellous

That will be a wonderfully authentic experience! Please let me know if it works ok, especially if there are colours bleeding from the HUD to the game area or vice versa (that will be a timing issue).

I tried the SSD on my Elk, but I got 'Bad String at line 74' when it was loading, when it executes *RUN LOADER. I have a Slogger Pegasus 400, RH Plus 1 ROM. Will try again when another release is out

Thanks for reporting. Sorry about that. I will test different configurations and fix that!

I just tested on Elk + Plus1 + ElkSD Plus1 and it works without any problems.
Is your configuration: Elk + Plus1 + Peg400? And are you loading the game from a real disc?

It's all good ! Couldn't spot any timing issues / bleeding (apart from my dodgy TV !). Really must sort that out !

Would play some more, but erm.... work got in the way !

Yes, Elk + Plus 1 + Pegasus 400. Could be a fault with my Elk I guess but not had issues with other games or your other demos.
