+Sun Electronics / Gifu Tokki G.T. Block Challenger
+(is "G.T." Gifu Tokki or an indication of table cabinet type like Taito with T.T.?)
+
+Hardware notes:
+- NEC 8080A @ 2MHz (18MHz XTAL, 8224 clock divider)
+- NEC 8228, 2*NEC 8255C
+- 4KB ROM (4*MB8518)
+- 256 bytes SRAM(2*MB8101), 1KB SRAM(2*M58754S)
+- 1bpp bitmap + ball sprite
+- discrete sound
+- 15 switches (not the usual small dipswitches, but separate large switches)
+
+TODO:
+- paddle sprite and missing (presumed) ball vs paddle collision detection
+- video timing is wrong
+- identify remaining switches
+- the flyer photo shows a green screen, assumed to be an overlay on a B&W CRT
+- sound emulation
