CPCtelera: Astonishing fast Amstrad CPC game engine

CPCtelera Logo

CPCtelera is a multiplatform framework for developing games and multimedia software for Amstrad CPC. CPCtelera runs either on Linux, OSX and Windows (with cygwin) and makes it easier to start developing games in C or assembly languages for Amstrad CPC.

CPCtelera is also thoroughly documented, has a complete reference manual and the code is comented in depth.

If you want, you can also get latest under-development versions from its Github.


Low-level programming API functionalities

Coding an example with CPCtelera
  • Draw normal and masked sprites
  • Draw solid colour boxes and speed up sprite trail erasing!
  • Reproduce audio and sound effects
  • Create fade-in / fade-out effects with your sound FX and music!
  • Mix-up sound effects with music, using the 3 audio channels for both at the same time!
  • Draw strings and characters using ROM characters without using firmware.
  • Change the complete hardware palette and individual palette colours
  • Draw very fast tiles aligned with character lines in the screen.
  • Change default screen video memory location (do hardware double buffering!)
  • Synchronize with VSYNC
  • Change Video Modes (0, 1, 2 and undocumented mode 3!)
  • Measure performance of your game loop (and know how many free CPU cycles you still have for doing more things in your routines!)
  • Scan the keyboard for pressed keys with the fastest keyboard scanning routine available!
  • Disable and re-enable firmware operation at will
  • Enable and disable lower and higher ROM access
  • Optimize array storage using bitarrays (arrays of 1-bit, 2-bit and 4-bit elements available!)

Project creation, management and integrated build system

CPCtelera sprite drawing demo
  • Integrated set of compiling and generation tools (SDCC 3.4.3, iDSK 0.13, Hex2Bin 2.0, 2cdt)
  • Easy and automated project creation and management
  • Automatic generation of CDT and DSK files
  • Program completely in C, completely in Assembler or mix both languages at will. You won’t even have to touch a line of the build system!
  • Automatic generation of obj/ folder with all the intermediate object files (Never mess up your src/ directory!)
  • Automatic generation of binaries, assembler output, symbol files and everything you need for debugging your program.
  • Automatic identification of your project source files in C and ASM (.c and .s). Add new source files to your src/ directory and they will be automatically recognized an compiled!
  • Automatic detection of src/ directory structure up to 1 level of subfolders without any modification!

Authoring tools and command line tools

  • Create your musics with Arkos Tracker
  • Create your sprites, tiles and maps with Retro Game Asset Studio 0.97! (And export them directly to CPCtelera C Array!)
  • Convert any binary file to C Array and include it in your project with cpct_bin2c
  • Convert a big sprite in a C Array into tiles of your desired size with cpct_sp2tiles!
  • Convert old sprites in assembler CPCRSLib format into C Arrays with cpct_rgas2c!
