TjLaZer has released new Amiga conversions of Dig Dug and Mario Bros., with disk and WHDLoad downloads available for both. The fan projects adapt Namco’s 1982 digging game and Nintendo’s 1983 arcade platformer for Commodore’s computers.
Both ports list a requirement of 512K Chip RAM and support PAL and NTSC machines. Their project pages disclose AI assistance with code during development.
Dig Dug is a new 68000 conversion supporting OCS, ECS and AGA Amigas. It uses arcade graphics, colours and round layouts, covering rounds one to 15 before continuing with the original game’s repeating stages. Music and sound effects play through Paula, the Amiga’s audio hardware.
The conversion includes Pookas, fire-breathing Fygars, ghosting enemies, falling rocks and bonus vegetables. It also retains the final enemy’s escape behaviour. A five-entry high-score table records player initials, while extra lives arrive at 10,000 and 40,000 points, then every further 40,000.
Dig Dug automatically selects its display layout. PAL mode fits the whole playfield on screen beside a score panel. NTSC mode instead scrolls a full-height playfield beneath a status bar across the top.
A joystick in port two controls movement, digging and pumping, with cursor keys and Space providing a keyboard alternative. P pauses the game, and S changes the speed setting. Escape returns to the title screen, where pressing it again quits.
Updates following the initial release have addressed excessive speed and an Escape-key crash. Version 1.4 also incorporates fixes for attacking ghosting enemies and shooting through thin walls, with updated standard and WHDLoad packages available.
Mario Bros. supports two players on separate joysticks
Mario Bros. adapts Nintendo’s original arcade game for Amiga OCS hardware. Its listed features include arcade graphics using the original colours, a 32-colour low-resolution display and the POW block’s screen-shaking effect.
The port supports one or two players. Player one connects a joystick to port two, while player two uses port one. Either the fire button or an upward movement triggers a jump. Keyboard controls give player one cursor-key movement, with Ctrl or cursor up for jumping.
TjLaZer lists a game speed of 60 game frames per second on both PAL and NTSC machines. The display has a separate setting: F5 switches between PAL 50Hz and NTSC 60Hz on machines equipped with an ECS Agnus chip.
Mario Bros. offers a bootable ADF disk image and a separate WHDLoad archive. Dig Dug provides those formats alongside a standalone executable for Workbench, Shell or hard-drive use. Its stated operating-system requirement is Kickstart 1.2 or later.
Both games are available on a name-your-own-price basis through TjLaZer’s Dig Dug page and Mario Bros. page.
