Happy New Year fellow VBLANK warriors.
As you might be aware 2018 is the 40th anniversary of the release of the Intellivision's little brother, the Unisonic Champion 2711. To celebrate I have tidied up Li'l Bro and added the four cartridges originally released by Unisonic:
Inside each game archive you will find three ROM images, suitable for JzIntv. These contain the Intellivision version of a single cartridge for use with and without the ECS and a musoCheat.rom containing just the in game ragtime music. In addtion, there is a JzIntv keyboard hack file, an overlay image, game instructions and box art:

In addition to the Li'l Bro version of the game for the Intellivision, a ROM is included that can be played in MAME using the Unisonic Champion driver. As well as the original two player game, a second version is included that replaces player 1 with a computer opponent that will complete each run in a world record 5.57 second time. Here are some piccies:
Under the hood Li'l Bro is still a simulation of the Champion, rather than an emulation. However, the new version has been completely rewritten. This time rather than manually porting the games, as was done in 2016, the core of each Li'l Bro ii game is constructed automatically using static binary translation. A Perl script has been constructed that reads each Unisonic Champion cartridge image and generates the assembly source code of an equivalent Intellivision game. The simple, atomic instructions for doing things like writing to the screen on the Unisonic have been replaced with subroutine calls on the Intellivision. In practice, wrinkles such as indirect addressing make this a little more complicated than it might at first seem. The converted game source code has been integrated into a framework for Li'l Bro and assembled. The result is about three times larger and slightly slower than the original version of Li'l Bro. However, it does have the winning feature of not being mind-numbingly boring and time consuming to convert games.
Anyway, 'enjoy' playing the games of the Intellivision's little brother and remember to look back for some interesting updates.
As always, all feedback, good, bad and indifferent is most welcome.
