FO 09:52 PM Back from holidays: I'm back from my holidays. I didn't find much time to work on this, a few hours here and there. The address decoder/bus master priority logic rework is taking shape and looking much neater - it was long overdue. I estimate about a days s... foft
FO 09:46 PM Feature #58: Maybe consider moving CART selection closer to top in F12 menu ?: Yes I agree this makes sense. I'd like a wider review/redesign on the firmware, there is a lot of scope for improvement. I'd really like it if someone else could pick this up so I could focus on the hardware aspect, any takers? foft
FO 09:43 PM Bug #57: Ballblazer playfield has issues after firing in v14: Pleased its a non-issue:-) Did you try this version on a real NTSC system? foft

ZZ 05:04 PM Feature #58 (Closed): Maybe consider moving CART selection closer to top in F12 menu ?: It seems to take more keystrokes/effort than necessary to joystick/arrow down to CART selection. (especially during testing)

ZZ 04:53 PM Bug #57 (Closed): Ballblazer playfield has issues after firing in v14: I'm seeing issues with Ballblazer on HDMI (NTSC), included in "Games Menu 1" on SDcard.
The playfield seems to desynchronize after shot is fired. (but it may take a missing shot or 2 to activate this effect?)
Can anyone else confir... zztop

FO 09:06 PM Bug #56: Galaxian Cartridge crash: This works on the latest core I'm using (lets call it v15 - address decoder rework!) foft
FO 09:04 PM Address decoding rewrite - tricky, tricky!: So I decided to rewrite the address decoding and priority access to fix the timing issues. Currently the 'address decoder' has a load of random stuff in it. Multiple bus masters come in (6502, dma and antic) and it chooses who has priori... foft

ND 10:06 PM Bug #56 (Closed): Galaxian Cartridge crash: i tried the physical 8k Galaxian cart on the Eclaire with Core v13 and the game crash 2sec into the demo screen
the same game in CAR format loaded form the eclaire menu works fine
its the physical cart that crash ndary

FO 08:14 PM Feature #55 (New): Replace main CPU: I really find the stack based zpu annoying to debug. Also as its setup the rom is full.
Consider replacing with something newer, also with gcc support, such as https://github.com/SpinalHDL/VexRiscv. foft

FO 08:11 PM 917k's setup!: I'm sure you've already seen Steve's great setup, but if not go and see here. Very nice work:-)
