ahh ok no wonder, god why do they make something new to not work with anything else I can't stand this!
Two reasons. First of all, their hardware supply for the flash chips dried up, so they had to make a change. Furthermore, you forget that the 3in1 was never originally intended to work with any slot-1 device except the EZ-V. GBA ExpLoader is entirely unofficial. It's not the responsibility of the EZ-Flash team to make sure that their product works with the unofficial tools. Now if the new 3in1+ didn't work with the EZ-V at all, then you'd have a problem.
