Slideshows on Tape
« on: 02:07, 10 December 19 »
Hello forum!
I'm just a regular guy with basically zero knowledge about programming that recently felt the urge (once more) to grab a CPC emulator and replay some of the games I owned when I was a kid.
The reason I decided to join the forum after years of lurking from time to time when the retro fever came back, is that some weeks ago I watched a video on Youtube about a guy that used to make tapes containing only loading screens, that the Spectrum would load one after another as in a slideshow. A quite slow one :D
I always liked or I should say learned to like the loading proccess of games on tape, even when I was a kid, the first time I saw a commercial game loading in my CPC was quite stunning. I was used to the standard loading routine based on blocks. So when I saw the borders flashing in colors ( it was a Dinamic loader ) reacting to the sound of the tape and after a while the "whole" screen filled with a picture it was impressive.
So this time I decided to make my own slideshow tapes.
I mentioned I have no idea about programming, not even basic, so what I do is a very simple loader that sets the inks and border colors, then with load"!" the screen loads and with run"!" the tape keeps running so it loads the next loader, the screen, and so on.
The screen just loads the standard way, though I learned that with CDT Master it's possible to create a screen file with only 2 blocks being the second a long one.
The only issue is of course, that the cpc standard loading routines doesn't have the border effects when loading, so i tried to find stuff about loaders, and how they worked, and man, I never imagined it would be so complicated. For someone like me that has 0 backgound in this world of programming everything sounds too arcane and obscure :D
So luckily in this searching about information somehow found the Java CPC emulator which with the option of "Drawing stripes on border" it emulates the effect of a turbo loader whatever it's loading so it almost feels like I'm running the slideshow on a professional loader.
But I'm curious about if it would be possible to do a slideshow turbo loader. I found turbo loaders in assembler that can be used to load games with their respective loading screens, but even with comments in the code, assembler is like chinese to me, I have no clue of what I'm looking at. So I wonder if it would be possible to do that, and if so how the loader would do to know which inks are used in each screen, or they have to be set like in basic (each screen would have its own turbo loader)
Also I know there are tons of utilities for transferring archives from disc to tape, but as far as I know they always convert archives into the standard blocks routine. Are there tools that allow to create a Speedlock or another kind of turbo file?
Anyways I should stop already, It's been enough textwall.
I leave here a sample of what I mean by a slideshow tape. It's a CDT with 3 pictures I made some time ago that I converted with Java CPC paint.
Thanks for reading!

Well, for those who enjoy and find the beeps, bleeps and scratches coming from data tapes relaxing may find this fun.
Here are the first 5 CDT's I made with loading screens from games.
Each one contains 10 loading screens. There's no particular order or theme, just nostalgic reasons or I think the screens looks nice or it's original or weird.I tried to recreate the original loading baud rate if possible. (not on many) I didn't own or played most of the CPC games in the day, and some screens are from games released as far as I know on disk only, or have peculiar loading routines that can't be mimicked this way so most of them will load at 2000 bauds.
I tried also to recreate the original loading routine if possible. The screens load the standard way, but between block header and data it's possible to add pure data blocks, pulse tones and binary files with random data that the standard loading routine will ignore, or mix headers and data from identical files saved in different baud rates, so if you hear Speedlock pure data blocks and uncommon bleeps, it's just stuff I added for fun  ;D Due to my absolute lack of knowledge in the matter I cannot include any cool loader, so if like me you want bars in the border use Java CPC emulator (the only I know that includes this feature) and check "Draw stripes on border" option.
Tapes 1 and 2 won't pause the cassette deck after loading a screen, but there's a pause block of 6 seconds + the next loader loading time wich is enough time to pause the deck manually if wanted.
Happy taping!

Heh glad that someone likes it. Since I posted the last time I made like 16 more tapes and a few compilations of screens of spanish studios, ( Dinamic, Opera, Topo...) so if you are interested let me know and I'll post them all.
If you're into tape loading then make sure you check out the demo Breaking Baud if you haven't already:
http://www.pouet.net/prod.php?which=62934

Yeah I knew that one already. Very impressive work. I wish there'd be more demos of this kind.

Well, Here are the next 5 tapes I made. Extreme on volume 9 has a wrong colour. Dark green (9) should be dark red (3)
I never thought this would be worth of a video :D
I wish Retro Virtual Machine would simulate the loading border effect. It seems to be the perfect kind of emulator to load tapes just for the sake of it. I hope they add it in the future.
Happy taping!

Hello again.
Here are the next 5 tapes with loading screens and as bonus, a compilation of the screens of the games released or published by Dinamic which I think are among the best ones made for the CPC (Not all but the majority)
Hope this helps to endure the lockdown a bit.
Happy taping!

 :o  Wow that is quite a lot of work, I just love the dedication you've put into arranging all those images in one CDT. It would take ages to load the Dinamic tape, so many images. Te lo has currado!  :)

Hello again bleep lovers.
Here are the first 5 slideshow tapes again and the Dinamic collection one, but this time with a nice pro loader that trocoloco kindly modified to load multiple screens. It's a modification over the already modified Topo loader, by Arnoldemu.

Credits for the Dinamic tape goes to trocoloco, which also added a nice Dinamic logo screen at the beginning.

Hope you like it and happy taping!

Here are the next remade 6 to 10 tapes.
BONUS: Loading Screens from IBER, a spanish company with only 7 titles in its catalog. Most of them (6 I think) spectrum ports. Even the screens are ported form spectrum excepting the last one. Yes even the only mode 0 one is a badly coloured spectrum screen. Their games were meh and of doubtful taste excepting maybe Casanova which was originally from Topo software. Enjoyable in its cheesiness.
Happy taping.

Certainly the only good thing about Iber was the awesome cover art by Juan Gimenez in four of their games. Casanova, Toi Acid Game, Defcon 1 and Ke Rulen los Petas. Among other spanish (generally better) games of its time.
Sadly passed away at 76 in April 3rd of Covid -19. Rest in Peace.
