Spectrum Computing

Quick play after work and I have all 3 Horace’s in 1 image. Renamed the “run” programs as the menu will be “run”, all went well until I renamed the hspiders one to “runspid”. I got an out of memory error. Renamed back to “run” and all was well. “Spi” works too, so I’ll stick with that. Memory must b...

Did you use the T2S file? https://github.com/skoolkid/t2sfiles/blob/master/t2s/0/3d-starstrike.t2s Just tried that myself and it does crash at the start. Easy to sort by using the -c option, I tried the printer buffer option first and it worked. z80onmdr 3d-starstrike.z80 -c p TomD Can't remember w...

I did make a 3D Starstrike mdr that went through with no errors but hangs on final running though.

Apologies Tom, it's the Skoolkit that hangs, I need to chat to Skoolkid instead

Thanks Tom,
I might need to chat sometime as there's a few snapshots that have hung z80onmdr this evening. Wonder if there's any options etc that might help?

So now I have all 3 Horace’s, I remade the HGS so it loads with the splash screen etc. I’ll combine them on one mdr with a little basic menu and consider it done

Lunar Jetman has also been processed, never liked it as a kid, actually bought the tape. Will add it to Jetpac and Tranz Am

Forgive the plug, but I'd recommend using SkoolKit's tap2sna.py for purposes like this: $ tap2sna.py https://worldofspectrum.net/pub/sinclair/games/h/HoraceGoesSkiing.tzx.zip Downloading https://worldofspectrum.net/pub/sinclair/games/h/HoraceGoesSkiing.tzx.zip Extracting Horace Goes Skiing.tzx Prog...

Thanks that mdr worked great, can you tell me what emulator you used to make the snapshot? Edit: I installed fuse and tried to snapshot horace and the spider, but got an error wgen creating the snapshot. I did it as soon as the tap file was loaded. Do I need to play through the game until it goes ba...

If you just modify that basic and change it to load from the microdrive does it look like it is trying to load from tape once it finishes?

Don't retype the code just save it to microdrive and modify it... then the actual numbers should be saved ok.

I’ll give it a try tomorrow

Just so you there's no confusion the output after line 50 is just a CAT of the microdrive

Having had loads of help successfully getting Jetpac onto microdrive (and vdrivezx) and have now turned my attention to my Mum's favourite Horace Goes Skiing. Trans Express nearly gets there, but there is a last bit of loading that still looks at the tape not the microdrive. If i play the tzx at the...

Interesting, would an eeprom fit in the pcb without modification, if so what eeprom to do use?

Adding in a few extra commands would be good too, the *MOVE and *CAT from the intro cartridge plus a RENAME option is a good start.

So true! The lack of hook codes to just LOAD/SAVE a file still annoys me to this day. I do like the drive 0 idea. One of these days I want to try rewriting the IF1 ROM, now the source code is available (TImex archive) Have you tried using Beta Basic v3? - it makes microdrive usage so much better. Y...

Nice to make it compatible with multiple drives. It's a shame you can't do LOAD *"M";PEEK 23766;"file" It's a real shame more thought was not put into developing the if1 rom. It had been me, as the system variable is available I'd have made LOAD *"M" ;0;"file"...

With one small change I got it working. As I was using a tzx and tape player I found that doing the initial load and break at the Jetpac is Loading caused the screen$ save to the hang. Skipped that load and all was well. I also modified the new loader to use peek 23766 so it would load from any dri...

Yes thanks, all sorted tucked up on a "ultimate" mdr along with Tranz-Am. Will add a simple basic menu some time.....

If you've only got a Spectrum, a microdrive and the Jetpac tape then the following steps should get you a working cartridge. The method used does require a 48K Spectrum. 128K users will need to use 48 Mode Insert blank microdrive into drive 1 Clear Spectrum memory with RANDOMIZE USR 0 Type in LOAD ...

I assume the initial LOAD at stage 2 is to be initialise something ?

Now you are talking, many thanks, I'll give it a go soon

If you are using a vDriveZX then you can use my Z80onMDR utility to create a microdrive cartridge with JetPac on which will do the conversion for you and remove the memory issue (https://www.tomdalby.com/other/z80onmdr.html). You can either create a Z80 snapshot yourself from a TAP/TZX (skoolkit or...

Hi, looking to get a working copy on my vdrivezx, when you say copy the code do you mean the original Jetpac2, 3, 4, 5 etc?

Any guidance you could give to a numpty like me would be appreciated

I understand about 25% of that

Looks like I need lessons....

To complicate things I am using a VDriveZX rather than a traditional microdrive

Hi, I guess this is a rookie question, but I am trying to get Jetpac onto microdrive and have failed. Tried Trans Express but an invalid file error when running, so I merged the basic loader from tape and edited the load line to include the microdrive version of the command and now get an out of mem...

And it's now on my vdrive, so if anyone wants an mdr file.....
