概 要6522 VIAシフトレジスタの問題。
詳 細there is currently an issue with the vectrex emulation.
this issue was not present in mame version 0.178 (apologies i don't know in which version of mame this issue first appeared).
currently in mame the vectrex emulation has a VIA bug, which is due to the shift register being incorrectly shifted every cycle.
the shift register should be shifted every two cycles (i have attached the information from the 6522 VIA datasheet showing this).
this current emulation inaccuracy results in text shown on the display being displayed as 'compressed'.
