Franky Mode 4 Development Tools 
Monday, January 18, 2010, 11:56
I've started a Franky Mode 4 Development page. Its main goal is to encourage new developments for Franky Mode 4 rather than just conversions of existing Sega Master System titles. It contains tools to convert SC5 pictures to Mode 4 tiles. Future releases will most likely include tools like tile and sprite pattern editors and editors for the name table and sprite attribute tables that will use Franky to display the result on. The site will also contain a list of links to third party tools (these may be running on systems other than MSX) that can be used to create tilesets and sprites for new developments.

R-Type Improvement Addition 
Sunday, January 10, 2010, 13:26
Some time ago a patch for an improved version of R-Type was released. However, that version did some changes to the game that may have given it a lighter interrupt handler, but it also tended to regularly crash during the game with MSX-MUSIC detected.

This version comes in an additional ROM image that requires the original game to run and start the game via a menu. It's available in the download section of my Home Page.

FIXBOOT v1.1 
Monday, January 4, 2010, 16:55
I've released an updated version of FIXBOOT. It fixes a small bug that caused disks/paritions with the dirty disk flag set not to be corrected and adds the option to force the Volume ID to be according the MSX-DOS2 specifications. This only works on FAT12 paritions.

Franky 
Saturday, October 24, 2009, 18:04
Today I received a Franky cartridge from Sander van Nunen after I offered to look into how things work with it. But first a few specifics...

Franky is a cartridge extension containing a 315-5124 chip, which is available in the Sega Master System consoles. This chip contains both a VDP and the SN76489 PSG. The VDP is based on the TMS9928A and extended with some console-specific features:
  • palette in 2 banks with 16 colors each of which 1 bank dedicated to backdrop and sprite colors
  • horizontal and vertical hardware scrolling
  • TMS9928 style tile patterns and sprites where each pixel can have its own color
  • line interrupt
  • extended name table with up to 512 tiles, options to mirror, flip, change priority (sprites will go behind it) and palette bank for a tile
  • flags to disable specific rows or columns from scrolling (useful for score boards in games that use scrolling)
  • access to horizontal and vertical counters
The audio exits 2-way, to the MSX via de cartridge slot and via de 15-pin SUB-D (VGA connector), which has the same pinout as the ESE3 for convenience purposes.

Right now many Sega Master System titles can be played when they get converted while the game files get loaded. Some titles have been converted manually already as the automated converter has problems converting those.
