Joy 2B+ support for ATARI 2600/XL/XE

[ascrnet]

First of all great job, I bought a blueretro adapter I found it very good and it works very well with my ATARI 2600/ATARI 800XL. Now I wonder if in the future it will be possible to add support for Joy 2B+ the modification is simple is to use the paddle pins to have a second button on ATARI 2600 and 2 buttons on ATARI XL/XE.

I don't know how feasible it would be to do it or you really can't. Here is the github of the project for more information.

after buying an esp32 mini and doing several tests I was able to activate a second button using the I026 I got it from the documentation, but I need another one for the third button I was thinking of using I033 which is used for the second joystick, the question is there a simple way to move it from joystick?

thanks to the documentation I was able to set up the development environment to compile without problems. I wanted to see if it was possible to modify the parallel_2p.c file and add the second joystick 2 button but to the one to not be modifying much the FW.

static DRAM_ATTR const uint32_t para_2p_btns_mask[2][32] = { { 0, 0, 0, 0, 0, 0, 0, 0, BIT(P1_LD_LEFT), BIT(P1_LD_RIGHT), BIT(P1_LD_DOWN), BIT(P1_LD_UP), 0, 0, 0, 0, BIT(P1_1), 0, BIT(P1_2), BIT(P2_2), 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, }, { 0, 0, 0, 0, 0, 0, 0, 0, BIT(P2_LD_LEFT), BIT(P2_LD_RIGHT), BIT(P2_LD_DOWN), BIT(P2_LD_UP), 0, 0, 0, 0, BIT(P2_1 - 32) | 0xF0000000, 0, BIT(P2_2), 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, },

The idea was to add the button to the first joystick but it does nothing, it ignores it. Something else I need to add or modify but I don't know where to mention it in case someone knows.

why not use parallel_1p if you need more buttons?

just out of ignorance, thanks for the tip I will try it. :)
