The project can be found here https://github.com/CycoPH/Mad-Assembler-CPP As for the translation, I used google (obviously the results are not that great). Step 1 in the process was to translate the Delphi comments from Polish into English. Then it was trying to figure out Delphi and translate the code. Delphi and C++ code are very similar. I intend to port any new changes over to the CPP version.

I wrote the Atasm Altirra Bridge because I did not know about Wudsn and I like working in VS Code. Lots of people use Mads with the Altirra Bridge. I'm busy with a port of mads from Pascal/Delphi into C++ so that I can add some export functionality.

Added a much needed feature to the Atari FontMaker. When in MegaCopy mode there is a clear indicator in the bottom right of the screen showing that you are in this mode. No more guessing and destroying your screens.

I'm busy investigating this. The idea is to write a 3D game that will run on the PICO but display on the Atari. The biggest limitation will be the low color count.

The logic parts are written in C. All drawing is done in asm

Retro Maze by Peter Hinz 2023 aka RetroCoder Source and binary available here: https://github.com/CycoPH/Atari8bit-RetroMaze Game idea The basic idea for this game was a coding challenge: to draw a 3D looking maze using just ASCII characters. With some extensive font modifications the result is RetroMaze. Play through 15 ever more complex mazes and find enough items to unlock the exit. You can find chests with useful items, ghosts that can be traded with or simply attacked for their loot, and vortex jumps that take you to new locations. Each level is unique never to be repeated. Interaction On the start screen use the joystick up/down to select your starting level, or left/right to select the difficulty. Press FIRE BUTTON to start the game. In the maze you use the joystick to move. Forward/Backward will move you in that direction. Left/Right will turn your view into the selected direction. Hit and hold the FIRE BUTTON to show the map and action menu. Release the FIRE BUTTON to activate the selected action. Map interactions Press and hold FIRE BUTTON, the view will change to show a top-down map of the walked maze in the middle of the screen, and a menu with actions at the bottom. The map shows your current location and facing direction. It also shows all the exposed parts of the maze. The game employs a fog of war technique, so you looking down a long corridor will expose a small number of maze positions. If you have not looked at it, it will not show on the map. The action menu at the bottom of the map screen will list the actions available to you. The list of actions depends on where you are in the map. At a minimum you will have the BACK and POUCH actions available to you. Note that you enter the map/action view by pressing AND holding the fire button. The first highlighted action is always BACK. When you release the fire button the selected action is performed. In the default case releasing the fire button on the BACK action will return you to the 3D maze view. So hit fire to show the map, release to return the the 3D view. Select a new action by pressing UP or DOWN on the joystick. The selection will change with each joystick push/pull. Release the FIRE BUTTON to activate the action. Pouch actions Select the pouch action and release the fire button to open the pouch. The pouch will show you how many BOMBS, MAPS and VORTEX actions you have available. Use the joystick left-right to select an action. Press fire to activate the action. Use joystick up-down to get out of the pouch menu and select something else. Vortex jump When you activate the VORTEX from the pouch you jump directly to the exit location. Unless you are at the exit location already, then you would jump to the middle of the maze. This is very useful to check what you need to collect to finish the level. Map reveal Selecting the MAP from the pouch will reveal the whole map. Every power pill, all chests and ghosts are revealed. Don't waste them, they become very useful in the larger levels. Place a Bomb Selecting the BOMB will switch back into the 3D maze view and a bomb will explode. The effect of the bomb will break a random number (1-4) of walls in the direction you are facing, so make sure that you select the correct direction before you place the bomb. Great for making shortcuts in the maze. The explosion will also affect any locked ghost, chests, exit. Try it and find out for yourself. Chest actions Walk up to a chest and hit the fire button. If the chest is locked you will first have to unlock it before you can open it. Hit the fire button to unlock, note you need enough energy, orbs, keys, etc to unlock the chest. Once unlocked you can take the three types of items inside. Vortex actions You can find vortex jumps in the maze. These will randomly place you at another location. Hit fire and select WARP to jump to a new location. Exit actions The level exit door is locked with two kinds of items. You need enough of each type to unlock the exit. Ghosts actions No maze game would be complete without ghosts. These are friendly but they do try to trick you when trading with them. Each ghost has specific trading options, and not all options are always to your advantage. The idea is that you use the ghosts to trade for items that you will need to open all the chests and unlock the exit door. You can use the TRADE action to interact with a ghost. Each type of ghost has special trade options that depend on what you have in your inventory. Once the TRADE action is activated, the GIVE/TAKE menu is shown. Joystick left/right cycles through the available trade options. Press FIRE to action a trade. Joystick UP/DOWN will exit the trade menu. ATTACKING a ghost is a quick and dirty technique to get hold of loot. It will cost you some of your inventory items to attack them, or try a bomb, but it will have consequences. Once attacked and looted the ghost will disappear and will not be available for trading. Switch actions The maze designers left behind some switches. Activating it will transform some of the maze. You may find that using them will make your travels much faster. Have fun and don't get lost retromaz.xex

Game idea Match the numbers, and colors, on the edges of the tiles by arranging the 9 tiles into the 3x3 grid. Once you have 12 matches the level is complete. Each level is unique never to be repeated. Interaction Use the joystick in port 1 to select your difficulty level. Up/Down selects the menu option; left/right changes the options. Press FIRE to play in the selected difficulty level. You can change the numbers on the tiles. 0 and 1 are the default (Easy). Try 0 to 9 for a little bit of a challenge. The color option switches between black or black and white tiles. The introduction of color makes the game a little easier until it gets more challenging quickly. Difficulty level adjusts the number of white sections, the higher the number the more white, the more difficult. Rotation is the kicker. If it is turned on the level generator will randomly rotate the tiles and you will have to rotate them to find the matches. The play field is divided into two areas. Left the 9 areas where you will place your tiles. Right the 9 tiles to be placed. Use the joystick to move the selection cursor onto a tile. Press FIRE to select the tile. It will show in the action box at the top. Move the cursor to the location you would like to place the tile and press fire to place it. If you want to rotate the numbers on the tile hold FIRE and press LEFT or RIGHT. Press the ESC key to give up on a level and return to the start screen.

There was a request that it would be good to show/use the inverse color COLPF3 in the character editor when editing inverse chars ( > $80). V1.6.9.0 (available on GitHub) now supports this. When using color PF2 and editing a character from the inverse part of the font then the editor will show the inverse color.

Here is a short play of RetroMaze. It shows some of the monsters and actions. Have fun exploring the levels. RetroMaze2023.mp4

Not an actual maze. Just a different view of the normal slash maze

I saw a this YouTube video and thought about an assembler implementation. Took about 15 minutes with come cut and paste. Source can be found here: https://github.com/CycoPH/SlashMaze theapp.xex

For those who love numbers and matching things up.

Phaeron you are a star It turns out that the I did the RMT music player routine first and then only did the DLISTL/H update later during the VBI. With some instruments the processing was too much and the display list registers were written too late. As it turns out the jumping was in tune to the music
