<br>== Copy Protection ==
== Loading music ==* [[Lenslok]]* [[Loaders]]
=== Cassette =Loaders ==
Loading from cassette effectively uses all the CPU's time because you have to keep checking the cassette signal to see if it has changed, and you use a CPU timing loop to calculate length of signal. * [[Loaders]]
So to do music and other things during loading requires precise timing. The C64 effectively had interrupt driven loading music and the serial chip handled clocking in of the data bits and signalled an interrupt when the byte of data was ready. == Games that can be started by joystick ==
<br> This is a list of games that can be started from joystick. There are not as many as you would think.
I think only Firebird games had loading music on cassette. The music was composed by Melvyn Wright ([http://www.melright.com www.melright.com]). The music data was embeded into the data on cassette. The data was read as a group of 3 bits and 8 data bits. The 3 bits determined if the 8 data bits were for data or for music. * Anarchy* Nebulus* Puzznic* Ranarama* Ping Pong* Donkey Kong
<br> == Programming methods used in games ==
This list is not complete, please add more. Will upload YM of the loading music soon. * [[Programming methods used in games]]* [[Guidelines for Programming games]]
<br> == Porting ==
Booty The method of converting game/data from one system to another, often with results that are not as good as if the game had been made/designed for the CPC from the beginning.

Spiky Harold [[Media:Spiky_harold-loader.ym|Media:Spiky_harold-loader.ym]]<br>== External links ==
=== Disc === The disc system on the Amstrad is "polled" which means the CPU has to keep checking if the FDC (NEC765) has more data to read/write. On the C64 the disc system is interrupt driven. So to do music while loading requires careful timing and often the use of very small sectors (128bytes). <br> ZapTBalls The Demo 5KB Demo 3 <br> <br> == Games Which use hardware tricks (on old generation cpcs) == Useful if you want to dissect games to work out how they did it. Please move to somewhere more appropiate <br> === Page Flipping === Most good * A look at 464 CPC games use the page-flipping technique in order to display sprites and/or scroll the playing area smoothly. In particular, two memory areas (instead of one) are reserved for the screen ram. In each frame, one of the two screens is displayed in turn, by using the hardware (exactly by changing the screen-offset, Reg 12 and 13 of the [[CRTC|CRTC]]). At the same time, the next frame is being drawn in the non-visible screen until the next frame fly back signal. Then, the same cycle is repeated for each following frame. The big advantage of this technique is that we can use a whole frame's machine-time for our code (with no animation problems that arise when we alter screen ram at the same time the electron beam displays it on the monitor). On the other hand, page flipping eats up a lot of memory area (which is crucial especially for 64Kb machines). This explains why a lot of games have very small game-areas ! === Hardware Scrolling === *R3 used to make an approximate byte lenght horizontal scroll (not really smooth) *R5 used to make smoother vertical scroll (1 line)Novabug{| class="FCK__ShowTableBorders"|-| ''Title'' | ''Year'' | ''Vertical'' | ''Horizontal'' | ''R3'' | ''R5'' | ''Confirmed''|-| [[Action Force|Action Force]] | 1988 | No | Yes | No | No | Yes|-| [[Anarchy|Anarchy]] | 1988 | No | Yes | No | No|-| [[Axys|Axys]] | 1991 | Yes | No | No | Yes | Yes|-| [[Bob Morane Science Fiction|Bob Morane Science Fiction]] | 1987 | Yes | Yes | No | No|-| [[Builderland|Builderland]] | 1991 | No | Yes | No | No|-| [[FlySpy|FlySpy]] | 1986 | Yes | Yes | No | No|-| [[Fusion 2|Fusion 2]] | 1988 | No | Yes | No | No|-| [[Gothic|Gothic]] | 1988 | Yes | Yes | No | No|-| [[Ghosts 'n' Goblins|Ghosts 'n' Goblins]] | 1986 | No | Yes | No | No|-| [[Jinks|Jinks]] | 1988 | No | Yes | Yes | No | Yes|-| [[Killer Cobra|Killer Cobra]] | 1987 | No | Yes | Yes | No | Yes|-| [[Led Storm|Led Storm]] | 1988 | Yes | No | No | Yes | Yes|-| [[Legend of Kage|Legend of Kage]] | 1986 | Yes | Yes | Yes | Yes|-| [[Leviathan|Leviathan]] | 1987 | Diagonal | scroll! | No | No | Yes|-| [[Le 5eme Axe|Le 5eme Axe]] | 1985 | Yes | Yes | No | No|-| [[Mission Genocide|Mission Genocide]] | 1987 | Yes | No | No | Yes | Yes|-| [[Monty Python's Flying Circus|Monty Python's Flying Circus]] | 1990 | Yes | Yes | No | No | Yes|-| [[Octoplex|Octoplex]] | 1989 | Yes | Yes | No | Yes(?) | Yes|-| [[Out Of This World|Out Of This World]] | 1987 | No | Yes | Yes | No | Yes|-| [[Paraplane|Paraplane]] | 1992 | Yes | Yes | No | No|-| [[Prehistorik 2|Prehistorik 2]] | 1992 | Yes | Yes | Yes | Yes | Yes|-| [[Prohibition|Prohibition]] | 1987 | Yes | Yes | No | No|-| [[Rick Dangerous 2|Rick Dangerous 2]] | 1990 | No | Yes | No | No|-| [[Roland On the Ropes|Roland On the Ropes]] | 1984 | Yes | Yes | No | No|-| [[Sentinel (The)|Sentinel (The)]] | 1987 | Yes | Yes | No | No | Yes|-| [[Skate Ball|Skate Ball]] | 1989 | No | Yes | No | No | Yes|-| [[Skate Rock|Skate Rock]] | 1987 | No | Yes | No | No | Yes|-| [[Skate Wars|Skate Wars]] | 1990 | No | Yes | No | Yes | Yes|-| [[Star Avenger|Star Avenger]] | 1984 | No | Yes | No | No|-| [[Stryker In The Crypt Of Trogan|Stryker In The Crypt Of Trogan]] | 1992 | Yes | Yes | No | No|-| [[Super Cauldron|Super Cauldron]] | 1992 | Yes | Yes | Yes | Yes | Yes|-| [[Titan|Titan]] | 1988 | Yes | Yes | No | No|-| [[Ultima Ratio|Ultima Ratio]] | 1987 | Yes | No | No | Yes | Yes|-| [[Warhawk|Warhawk]] | 1987 | Yes | No | No | Yes | Yes|} === Rupture (or splitscreen) === A technique to split the screen into more than one block vertically.
