I've been stuck for several days with a flu with only a MacBook laptop, and unable to test Mecha-9 and other games sent to me because the available emulators just doesn't handle VDP nuisances, Megacart and even less Super Game Module.
So I ported my private emulator with support for Megacart and Super Game Module,
It's pretty simple but it works like a charm at least in my Mac, and you can play any game from the original ones till Pac-Man Collection
I don't intend to update it in a looong time, so enjoy it!
Edit: Feb/15/2016 v0.6.4, now ADAM keyboard can be fully configured (very useful for users with non-US keyboards), and finally Raspberry version compiled.
Edit: Jan/11/2016 v0.6.3, better emulation for Z80 solves pitch problem in speech in Sewer Sam and Squish'Em Sam, keys F4 and F7 are now configurable, Expertype and ADAM Bomb 2 are now working, fixed some ADAM keys for Windows, added 64K RAM expansion for ADAM, fixed bug in joystick support (not tested), added code to show joystick movement when using F7 (show codes). Raspberry not updated in this version because I didn't found my external keyboard
Edit: Nov/27/2015 v0.6.2, solves small bugs in Z80 and VDP emulation. Ctrl+Fn+F4 creates debugging snapshots. Allows to use two keys to activate one button (both pressed at same time). Allows for two keys to activate same button (for example two controllers). Raspberry now shows status messages (important for F7 key codes). More keys are configurable: video recording, audio recording, screenshots, enable/disable roller controller. When using Roller Controller the sensitivity has been adjusted (was too fast).
Edit: Nov/05/2015 v0.6.1, small bugs fixed. Pause and Reset key couldn't use joystick. Better compression for AVI and safeguard if 2GB limit is reached. PAL switching didn't update BIOS European byte. Able to exit using # and * key at same time (only Raspberry)
Edit: Nov/04/2015 v0.6.0, all platforms updated! Added fast startup of Colecovision BIOS, Roller Controller enabled/disabled with only Fn-F5, VIDEO RECORDING!!! using Fn-F6 (AVI with ZMBV codec, playable with VLC Player), support for Right Shift + Enter to exit in Raspberry PI (useful for Retropie).
BTW, several people has donated to CoolCV for the Mac version and also for the Raspberry version, including a Raspberry PI (still stuck in snail mail) but I've got another one for the development using the donations Thanks for contributing!!!
Edit: Sep/23/2015 v0.5.4, Mac only, allows controller mapping to be changed (creates Documents/coolcv_mapping.txt), changed Fn+F7 to show instead key codes and joystick button codes, support for Super Action Controllers (you need to activate buttons in mapping file).
Edit: Sep/01/2015 v0.5.3, Mac only, added Fn+F10 to save PNG screenshots, now also checks for file numbers previously used and doesn't rewrite them. Now also accepts dropping ZIP files, the first ROM/COL/BIN file inside will be used as game ROM
Edit: Aug/31/2015 v0.5.2, Mac only, documented Fn+F8 feature to accelerate disk/tape read in ADAM mode. Added new feature to record audio files using Fn+F9, it saves files in your Music folder. Note it reuses numbers if re-run, so copy any files you like. Now you can use Q*Bert sounds for your cellphone calls, for example
Edit: Aug/25/2015 v0.5.1, highly experimental Raspberry PI version now available in post #91 http://atariage.com/forums/topic/240800-coolcv-emulator-for-mac-os-x-linux-and-windows/page-4#entry3307835
Edit: Aug/08/2015 v0.5.1, controllers should feel smoother now. Solves a bug in VDP collision register (failed in Carnival) and also allows to run Super Donkey Kong prototype (1983) deactivating SGM support (it crashed because the game wrote to port 7FH) (now ZIP file includes all platforms)
Edit: Jul/31/2015 v0.5 Added keypad support for controller 2 in keyboard and experimental Coleco ADAM support for DSK and DDP (check Read Me file for details) I've tested only SmartBASIC, Dragon's Lair and Donkey Kong Jr. (Aug/01/2015 added Linux and Windows versions)
Edit: Jul/29/2015 v0.4 Now supports for controller 2 in keyboard. Higher audio volume. Also implemented support for two joysticks (tested by grips03) with Fn+F7 to switch buttons and now it can launch ROM files (use context menu in your ROM file, select get info, change application to CoolCV, change for all) though not sure why there is a small delay in launching. Jul/30/2015 just added Windows and Linux versions.
Edit: Jul/26/2015 Now also compiled for Linux, 32 bits and 64 bits be sure to run the right version. Also you need to drop your ROM file into the window. If it's running slow, make smaller the window.
Edit: Jul/25/2015 I compiled this for Windows (very early). Same as Mac version, but you need to drop your ROM file INTO the window. If it's running slow, make smaller the window.
Edit: Jul/24/2015 v0.3 I've made this an integrated app for Mac. Now download it, open it, then drag&drop your ROM file over the icon appearing in task bar (bottom of screen). In fact you can put the app in the Launchpad for running it easily (no more command line!!)
Edit: Jul/23/2015 v0.2 ok, I didn't resisted the temptation to add window resizing and full screen mode. Snapshot saving/restoring. -pal option. And improved aspect ratio.
