Does 68010 mode really work?

[harbaum]

Here cpucfg[1] enables the tg68k which supports 000,010 and 020:

Minimig-AGA_MiSTer/rtl/cpu_wrapper.v

Line 141 in 99ac3ce

if(cpucfg[1]) begin

otherwise the fx68k is selected.

But here

Minimig-AGA_MiSTer/rtl/userio.v

Line 425 in 99ac3ce

wire cpu_cfg_sel = (cmd[3:0] == 4); // XXXXKCTT || cpu config | K - fast kickstart enable, C - CPU cache enable, TT - CPU type (00=68k, 01=68k10, 10=68k20)

the mapping is 00->68000, 01->68010 and 10->68020

So to my understanding this would select the fx68k whenever the 68010 is to be used.

You are right. After many rewrites 68010 kind of lost.
Is there an app/game to test 68010 mode?

As far as I know, the main difference of 68010 is VBR. It is needed for WHDLAOD. There are also a couple of utilities that can control it. https://www.whdload.de/docs/en/need.html

i've pushed the changes. Note: since now TG68K is used for 68010, this mode is not cycle accurate.

Pushed changes to Main to enable 68010 mode.

The tests from the vAmiga Test Suite could be used: https://github.com/dirkwhoffmann/vAmigaTS/tree/master/CPU/68010
Each test consists of an ADF and reference image.
