I have some syscoin from 2017 and I used the Blockmarket wallet. I recall when I logged in it showed different items for sale etc. I cant find the download for this wallet so I can convert it to 4.0. I did find an older version of sys wallet 2.1.5 which i did pull my .dat file into and it shows the coins being received but doesnt have any dump options. Any help would be greatly appreciated.
