Xyphoe did find two years ago an exploit, also found Green Beret, to easily finish levels in the Robocop game. He is doing it in this new video. This exploit can also be done on a ZX Spectrum, in both computers only the levels 1 and 3 which are withough heights. So you just have to keep 4 enemies behind you, and you will have no boss at the end of the level.

Reading commentaries of the video is interesting as the one by Roi Eclair who wrote : here's actualy another exploit you can do to get infinite energy, but so far i've only been able to do it with the bikers. you need to be almost dry on energy, and kill the biker right when he will hit you. you'll be out of energy, but still alive, and able to end the level taking any more amount of damage you want within the remaining time allowed. found this one by pure accident when i was a kid back then. may not be that easy tu pull, but once you get the right timing, you can be invincible. works on the cpc version, never tried on specy.

For Green Beret, as there are at most 3 sprites of ennemies plus yours, just find 3 ennemies going the same direction than you and you can go to the end of the level easily.

The last version of the Amstrad CPC emulator CPCEPower by Megachur is available on cpcwiki.

The goal of this emulator is to emulates as best is possible the Amstrad CPC, like ACE.

Aeon is a game written with Multi-Platform Arcade Game Designer 0.7.10 originally for the ZX Spectrum. It has been converted for Amstrad CPC by VincentGR and Kukulcan, music conversion by SuTeKH and help by Kees Van OSS. The game includes 4 mini-games (action, platform, labyrinth).

Xyphoe has played the game in a recent streaming. Better use this link than the video below as it starts at 35 minutes and 31 seconds.

PunyInform v2.6 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.

Budrumi is an Amstrad CPC graphical adventure game by Sakis Kaffesakis and Manossg, which you can see the solution on Youtube if you are stucked.

On Serdashop you can found audio and video cards to be used mostly on PC. For example there are two cards which are connected to the parallel port of a PC, especially those which can't use ISA/PCI sound cards such as old portables :

• OPL3LPT which uses a Yamaha sound chip : OPL3 which you can found in many msdos sound cards starting with the Sound Blaster Pro 2.0). You can see the OPL3LPT being used wit the Police Quest 3 demo
• S2P, which permits to use General MIDI. MIDI was at msdos time the best sound ever, but MIDI expander were not cheap. You can see the S2P with the game Betrayal of Krondor (nice music)

Pulkomandy has created a card for Amstrad CPC(+) : Willy which lets you use an OPL3LPT or S2P on it. He wrote two programs to use the OPL3LPT which you can found on his page :

• SA2 Surprise! Adlib Tracker player by Madram
• VGM player by PulkoMandy (uncompressed VGM at the moment)

Check the CPCWiki thread for more informations and short videos of the Willy + OPL3LPT being used.

By the way, there are other ways to use MIDI on an Amstrad CPC, but it will be for another day (hint, use serial, usifac, LambdaSpeak...).
