It is a bit too early to celebrate the 30th birthday of the CPC, but it isn’t too early to start a call for demomakers. The CPC demogroups Benediction and Vanity want to create a megademo which will be released in 2014 and they want YOU to participate. There is still plenty of time left, so don’t be lazy and register on Push’n’Pop for the competition!

Here is the original message from the Push’n’Pop website:

“To celebrate the 30th anniversary of our beloved CPC, Benediction and Vanity are proud to invite you to participate in the 30 years CPC megademo project! The aim is to build a new classic CPC megademo, with screens from any demogroup, and release it in 2014.

The megademo comity will be in charge of managing the project, coding the menu, linking and releasing the megademo with the utmost respect to the deadlines set. We will provide technical specifications or limitations as soon as possible (i.e., reserved memory, …) and support to ease the integration of the various demo-parts.

Rules

  1. The megademo must be developed in a friendly, funny scene atmosphere, by sceners that really want to promote the CPC.
  2. Your demos might not have to use state of the art demo effects, but crap-parts won’t be accepted (i.e. bad screen frequency, no novelty at all, boring, …).
  3. Demos written in Locomotive BASIC won’t be accepted.
  4. This is an Amstrad CPC megademo. Amstrad Plus-only demos won’t be accepted.
  5. Only one demo per group.
  6. Your demo must run perfectly on CRTC types 0 and 1, and also support type 2 as best as possible. Exception to this rule could be made for demos showing mindblowing CRTC-specific pr0n effects, but we would prefer not having such demos.
  7. The recommended format is the uber-classic-one-screen demo-part, but this is not mandatory.
  8. Demos that do not respect the rules and/or specifications won’t be accepted.
  9. Public previews are forbidden, except on the initiative of the comity during CPC meetings only (in order to improve quality of the megademo).

Deadlines

SATURDAY MARCH 31, 2012: Registration end.
SUNDAY JUNE 30, 2013: Final version of your part sent to the comity.”

The SDCC C cross-compiler is now available in version 3.0.0. It is also possible to produce binaries for the Amstrad CPC with it (see this CPC Wiki article). Here are the features of the final 3.0.0 version:

  • sdcpp synchronized with GNU cpp 4.5.0
  • changed z80 and gb targets object file extension to .rel
  • special sdcc keywords which are not preceded by a double underscore are deprecated in sdcc version 3.0.0 and higher. See section ANSI-Compliance in sdccman
  • xa51 and avr targets are disabled by default in sdcc version 3.0.0 and higher
  • introduced new memory model huge for mcs51 to use bankswitching for all functions
  • removed generation of GameBoy binary image file format, rrgb map file format and no$gmb sym file format from sdld linker. Utility makebin generates GameBoy binary image file format, utility as2gbmap utility converts sdas map file to rrgb map and no$gmb sym file formas.
  • implemented __builtin_offsetof
  • asxxxx / aslink renamed to sdas / sdld and synchronized with ASXXXX V2.0
  • majority of sdcc run time library released under GPL+LE license

A little bit late, but anyway: Artaburu released a new version of his utility library for the Z88dk C compiler. E.g. Mariano the dragon or the recently released Nanako Descend To Hell was written with this library and so it contains a lot of graphics functions, key functions, map functions, etc. You can download it from the official homepage of the CPCRslib.

Here are the changes since my last posting:

11/28/2010

cpcrslib with horizontal scrolling capabilities is uploaded. From now, there will be 2 official libraries: one for scrolling and one for static screen. Although the scrolling one can be used to for static screens, because it has been improved for scrolling, when static using it is a slower than the "standard" one. Horizontal scroll example included.

Bug in cpc_WyzPlayer corrected. When saving the player interrupt jump, the code was being corrupted due to a bad definition of the address where the original jump was being saved.

cpc_PrintGphStr0,cpc_PrintGphStr0M1: Optimized code: Smaller and faster, thanks to Kevin Thacker for coding it on Blue Angel 69. cpc_PrintGphStr2X,cpc_PrintGphStrXY2X,cpc_PrintGphStrM12X,cpc_PrintGphStrXY2X: New routines for printing graphical text at double height. Sample 5 modified.
