PunyInform v2.7 by Fredrik Ramsberg and Johan Berntsson to write text adventure games

-

PunyInform v2.7 by Fredrik Ramsberg and Johan Berntsson is a library written in Inform 6 to create adventure game (pure text, no graphic support contrary to DAAD) using the Z-machine virtual machine which will run on 8bit computers (or more recent computers too). PunyInform has a parser, knowing of common verbs and a framework to write adventure games.

PunyInform is based on the Inform 6 library written by Graham Nelson. Its goal is to make easily adventure games in Inform 6, with a manual describing the differences between the official library and PunyInform..

Games using PunyInform can be compiled in z3, z5 and z8 format (z3 being the best format for 8bit computers, other formats have more features). Compared to the Inform 6 library, it means that there is no support for the Glulx virtual machine but z3 format is important as Inform 6 doesnt support it.

To compile games written with PunyInform, you should use the Inform 6 compiler maintained by David Kinder. Binaries are available on if-archive. PunyInform needs Inform v6.34 (or more).

They are tutorials to write adventure game with PunyInform (end of the page).

To try your game after compilation, you can use WinFrotz by David Kinder, to create map easily you can use Trizbort.

New updated PC1512 Sierra SCI 16 colors driver by ripsaw8080

-

There was already in the Sierra adventure games a mode to support the special 16 color mode of the Amstrad PC 1512. This driver has been updated by ripsaw8080 :

  • scrolling issue resolved so no more screen corruption: instead there are screen transitions that are better suited anyways for the slow PC1512 (additional changes were needed in the driver's dispatch routine to preserve the value of the DI register)
  • color issue that resulted in unreadable areas is now resolved so newer EGA games are now readable (issue was the driver inexplicably reporting support for 65535 colors instead of 16), this made some later EGA titles playable: KQ5, SQ4, PQ3, SQ1 remake, LSL1 remake
