Spectrum Computing

Effects looks fine on my grey +2 through RGB/SCART into an LCD TV. Background is very solid. Player sprite is a bit shimmery as it's constantly animating but it looks good. Scrolling around is fine too. One of the frames of animation when rotating the gun round has a horizontal 8 pixel line that sho...

This seems to work -- and I very much appreciate your time looking at it. Yes, Rockfall 1 has some underlying BASIC (Rockfall 2 doesn't) and there's a lot of LET s$="(yuuu) (diii)eddd" lol to support the Currah speech. There is also one particular Currah speech that plays when you get the...

New version available here . (deep breath) v1.00 100% assembly rewrite of the browser to further reduce size and improve overall performance. NMI handler wasn't copying the 'real' bytes in bank 10 from 65024 - 65535 when it restored that section of memory. If you had POKEd that area of memory, the c...

I've re-uploaded a version which no longer crashes when you lose a life. When you lose a life the code sets the stack pointer to a value held in $5b88. On 48k machines this address is inside the printer buffer area at $5b00 which is a safe area to store your own data and code. 128 BASIC however uses...

Thanks but you seem to have screwed something up here. I get errors like "J Invalid I/O device" when simply playing the game normally. And once it crashed/hung with no way to get out. I've re uploaded my .tap file with ketmar's additional POKES. Completed the 1st level okay but it still b...

This should work when loaded from 128k now. The original loader was one large CODE block loaded from 16384 which stomped over the printer buffer which 128 BASIC uses for paging. I've also applied my patch for the sound effects.

For example why does this crash? What is happening? (recording of Rockfall Designer tool) https://cl4.org/__2023-12_rfdesigner_death.rzx When you collect the diamond, the code enables IM2 and jumps to an interrupt function at $fa01 which looks like it's sending data to the AY registers to do the so...

Are you directly calling the ROM tape load functions? When an esxDOS dot command is executed the normal ROM is paged out as the dot command is loaded into address 0x2000 / 8192. It is possible to call ROM functions when the esxDOS ROM is paged in with the following bit of assembly: rst $18 defw <add...

Hi, I know about the 426 files-in-folder limit, but is there a limit on the number of folders themselves? I'm currently struggling to put a large number of files on a vhd (~950 files in 275 directories, each of which has one subfolder). Files and folders are represented by the same structure so you...

Hi @bob_fossil , Just tested spt files support and the playback quality is really good as before, but I was surprised by some graphic artifacts in music folders, when I use the up/down arrows during playback to go to the beginning or end of the file list. After that, various visual effects occur (b...

New test version available here.

This should fix the reported graphics glitch when certain long filenames spill over the screen.

Thanks for the clarification, Bob. I also tried a lot of files in the /SPECCY/TAP-FIX/ folder, but none of them could be renamed. Does this explanation also apply to them ? It's easier to list the files that are 8.3 in that folder. :) ACE88-48.TAP BLACKMA1.TAP BLACKMA2.TAP FOXFBACK.TAP HADESNEB.TAP...

Hi, Bob, PM with my test image has been sent. Thanks for the image. The renaming code is worked as expected. Using my test program it appearsthat all but one of those files in your folder have long file names. The only 8.3 filename I can see is AMC-A.PZX Even short filenames like Cobra.pzx Batman.p...

Hi @bob_fossil , I have a possible issue and a question. It's a visual glitch that corrupts the first letter in the file name, when I scroll the file list with the right arrow, page by page. In my case its a folder with a couple of dozen pzx files and when I press the right arrow several times and ...

No need to apologise. Was nice to revisit some demos that require Pentagon timings to check it was still working.

Dont work very well. System freezzy when i save configuration in slot 3 (maybe 3 minutes or more with red led on). Finally operation ends well. Works, but spent much time to save or create slot. I've just tried saving and loading slots with v0.99a4 on my ZX-UNO and didn't find any issues. Loading a...

Does it work again in v0.99a4 if you replace the _UNO file in the BPLUGINS folder with the _UNO file from the v0.24 release?

Hi Bob, thanks for your great work on this application. I have detected that the ZX-Uno custom options are not being recorded in the slots. Does changing options from the main window still work - can you change the video timings, CPU speed etc? I don't suppose you know which version this stopped wo...

Can you please add to ZIP package also TXT info about used DIVMMC ram pages ? Now may be on DIVMMC used more than 128kB we need info about software expansion. This is already included in the plugins/plugins_sdk.txt file. With new CPLD firmware(2023): - on DIVMMC 128kB is used ram 0-4 for ESXDOS, ra...

Head Over Heels.

New test version available here . This adds support for Sound Tracker Pro (.stp) music files. Debugging this new plugin also uncovered a bug introduced during the assembly rewrite which stopped the browser navigation keys moving to next, previous, first and last songs correctly during playback. This...

New test version available here.

This should fix the reported issue with Kempston joystick right / page down not working correctly.

.brwscfg works for me. I've tested it on my +2 and under 128k emulation in Fuse and not encountered any issues.

New test version available here.

This should fix the reported Kempston joystick issue and the clipboard paste command which got broken in the assembly rewrite.

New test version available here . Bumped version to 0.99 as this is now a full assembly rewrite of the existing code and I wanted to differentiate it from the current version. I'm expecting bugs and broken features but these will be ironed out before I release version 1.00. I haven't exhaustively te...

This is way off topic, but does bobs browser work on a standard divide like the 57c I have? I've got it in my head that it doesn't. I don't own a divIDE but I have had reports and seen YouTube videos of people using my browser with it. After copying over the modified BIN and SYS files from the brow...
