Feature #58
closedMaybe consider moving CART selection closer to top in F12 menu ?
0%
Description
It seems to take more keystrokes/effort than necessary to joystick/arrow down to CART selection. (especially during testing)
Wouldn't it make more sense to move CART closer to top of selection, or maybe default to it when entering F12 screen ?
Unless there is already some sort of secret hotkey available ?
Thanks for consideration!

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?

Following the flash support, decided to split the menu into two parts:
i) Device emulation (disk + cart + usb stuff)
ii) Settings (video settings + rom + ram size etc)
+ removing the quick select menu.
The device menu is thus much smaller, easier to navigate.
Next up (bit beyond this ticket)... will add:
i) hotkeys 1-4,C to go to cart + disk selection (from device menu)
ii) type any letters to filter filenames in file selector
iii) Multiple profiles of os+basic+ram etc.
While in this space I started storing the default roms in the flash chip. So with no sd card get the os + basic + freezer rom (version in sof unused... might leave it for sim)

Loading of profiles is working (no hotkeys yet).
Saving is failing... I have to read 256KB of flash to sdram then rewrite with a diff, guess that is failing somewhere.

Doh. Writing in 256 byte chunks increasing destination address each data, but not increasing data pointer! Oops! So working now, but takes 7 seconds to save (v1, v2 not tested). Not much I can do about that on v2 (256KB sector size) but could be improved on v1 (4KB sector size).
So now I can load/save settings and have profiles.

Well, I can increase the clock speed of the spi communication. I'm only at 25MHz and think I can go to 100MHz. But not sure how much time is spent in spi overhead and how much time waiting.

M25P (54MHz max), N25Q (108MHz max) I think. Thinking I should really move away from the M25P (or equiv) for v2 fix, its pretty bad. Large sectors and slow.

Added support for filtering in the file selector. Also added hotkeys to the device menu (1-4 and C).

On second thoughts, one more feature to add here.
Updating of roms on the flash by loading/then save all.

Was getting tempted by a bigger rework, including settings in json: https://github.com/quartzjer/js0n
More work than my interest on this today!
