Hey Dean, fancy meeting you here!

Trying to download bbcsdl20.zip from http://www.bbcbasic.co.uk/bbcsdl/index.html But failing with "invalid zip file" while using the Windows built-in unzip and also with 7zip. Strange. Try this Dropbox link instead. What sometimes happens is that the download fails, but every time you repeat it you...

Excellent! How can I see this in action? If you have a PC, Mac, Linux box or Raspberry Pi (3 or 4) you can install the (free) BBC BASIC for SDL 2.0 and paste this program into the IDE: ENVELOPE1,1,0,0,0,0,0,0,127,-127,0,0,64,0:ENVELOPE2,3,0,0,0,0,0,0,127,-127,0,0,100,0:*tempo 1 MODE7:VDU28,6,24,32,...

I have no way to test this. But here's my best guess. I added WAIT at 2 different places I found a better way of limiting the speed, without using WAIT or INKEY, by modifying one of your SOUND statements! This also fixes another issue with running it on a non-Beeb (or Electron) platform, that your ...

I had another go in MODE 7, which I found easier to play as it was easier on the eyes, and achieved another high score.

Great score! And clever modification to MODE 7. I deliberately chose MODE 6 because I want it to work on the Acorn Electron.

Excellent Simon! It does get a bit tedious after a while doesn't it? :lol: At one point an enemy (ghost?) walked right through me, and I managed to stay alive. I don't know how that happened. Yes, this can happen. I thought I fixed it at one point but now I just call it a survival strategy feature ...

I gave up playing at 3091 score after I don't know how many levels. I was still in-game but my fingers were cramping.

Excellent Simon! It does get a bit tedious after a while doesn't it?

I added WAIT at 2 different places (I aim to keep each line max 120 chars). I can work with that, thanks. Using INKEY for a delay would be more universally compatible, and has the valuable side-effect of stopping the keyboard buffer filling (which can cause an annoying beep on some systems) but adm...

Would *FX19 do? Would that be enough delay? I could use an equivalent (e.g. WAIT or *REFRESH in those BASICs that support them) if so. Where should I put it? I have no way to test this. But here's my best guess. I added WAIT at 2 different places (I aim to keep each line max 120 chars). Choose eith...

Meet @-man, a Pacman look alike. I appreciate that it's intended only for a Beeb or Electron but it looks as though it would work on other versions of BBC BASIC if it included something to slow it down to a usable speed. Is there somewhere that an INKEY() delay could be added to achieve that? Would...

Scored 843 but I think this might be a game of patience and endurance.

Well done!

Impressive stuff!

How large was the program before you crunched it?

Thanks! Actually, I didn't crunch anything, I just wrote it this way (gradually of course)

Thanks! And yeah I should have mentioned those keys of course.... whoops

Excellent . . . I packed it for you and saved 3 bytes - still works . . .

Think of all the extra features I could add!

Any chance of a beeb disc image please? Chances of me typing that lot in correctly are slim at best!

Added to original post for your convenience!

I have put my ElkSD-Plus1 in my Electron and loaded the PresADFS and the Acorn ADFS-P3 into the SWRAM on the cartridge and it all loads & works fine with the Pegasus. I *UNPLUGed the Pegasus DFS before loading the ADFS to minimize the possibility of conflicts, but it still worked fine after *INSERT...

Thank you Ray and hoglet and DaveH!! =D> As it turns out ADFS103.ROM (from Ray) is the same as ELK103.ROM (from hoglet) and this is the only ADFS ROM I can make "stick" in the 16K bank of SWRAM in my ElkSD-Plus1. I have no means of creating a physical ROM myself (but DaveH is sending me a new ROM wi...

On my bucket list!

I have a stack of old floppy disks that I now want to transfer to SD-card using Electron/MMFS/Pegasus400/DFS. The problem was that none of the versions of IMTOD and IDTOM (disk imaging tools for copying whole disks from DFS to MMFS and vice versa) are compatible with the Electron. Until now that is....

That would be great, Dave, thanks!

Here is the corrupted ADFS 1.15 ROM:

I definitely found an issue with the ADFS ROM v1.15! I did a binary comparison of the entire 16K against the version from STH. There are single bit corruptions at 9 different locations in the 16K file. One example at offset &C40: mine has byte &00 (BRK) which should be &20 (JSR) which would definite...

Five! . . . OK, probably eliminated that train of thought

ROM corruption: Do you have anything that can read the ROMs? I can provide you with a known working image. So you could then read the ROM you have and do a binary compare.

*SAVEROM will do? Let's try it!

Hmmmm! I wondering if this is tied-in with the problems we were seeing at ABUG e.g. we were seeing issues with a 27152 (programmed with ADF 1V5 in all 4 16K blocks) in your Electron but not in two other Electrons! Do you know anybody with an Electron that lives near? Nobody with an Electron in my a...

If you are feeling brave, there is always my Elk port of BBC ADFS 1.30: https://github.com/hoglet67/ADFS130/releases Feeling really brave at the moment. ELK103 does work from SWRAM in the ElkSD-Plus1. And my Elk show "Electron ADFS" on startup. However, same as with the hacked ADFS 1.35, it doesn't...

One small step... I found this: https://stardot.org.uk/forums/viewtopic.php?f=3&t=2765&p=22597#p22608 This is a patched ADFS 1.35 for the Elk. It does work from one bank of SWRAM but it does NOT get my physical disk drive spinning. I can now switch between DFS (ROM in Peg400) and ADFS (SWRAM in ElkS...

Are you write protecting the sideways RAM after loading?

Mark

I was thinking about that (had the same issue before with my Master) but I don't know how to do that on the Electron with the ElkSD-Plus1. Or if it is even possible.

Just out of interest, have you tried it without the pegasus eeprom in there? Yes, I have tried it today. Same problem. I switched the ADFS ROM to the other bank in the Peg400 (and adjusted the links accordingly) and still the same problem. Then I thought, let's try my ElkSD-Plus1 together with the ...

Not sure what device is in 0xC0DE's Pegasus. The original (27C512) was replaced at ABUG to fix a problem that showed up on both of his Electron systems but not on mine or others!!

This is the ADFS ROM in my Pegasus:
