Virgil Dupras	d3049b2404	grid: add XYMODE ... In VE on the SMS, the first contents line would always be cleared because of NEWLN being called when the FBUF would spit its last char. Inconvenient... I've added a "graphical" mode to the grid subsystem to inhibit this behavior in a graphical situation such as in VE. Also, write a more complete Grid documentation.	2020-11-14 22:35:08 -05:00
Virgil Dupras	d1718a90c7	sms: add support for VDP's text mode ... Because that mode behaves exactly like in a regular TMS9918, a new driver for TMS9918 has been added in blkfs and SMS' VDP now uses it. Also, fix broken 5x7 font.	2020-11-13 12:18:00 -05:00
