One improvement is that it now uses a genuine OPL3 chip for the FM music. Furthermore it is all SMD components and hence very compact and will fit also in cases where space is an issue. But is it worth the money? How does it hold up against other homebrew sound cards?\r\n\r\nSonic Buster 8: https://labs-lv.github.io/sb8/\r\n\r\nJoin me on Mastodon: https://chaos.social/@root42\r\n\r\nSupport me on Patreon: https://www.patreon.com/root42\r\nSupport me on Ko-Fi: https://ko-fi.com/root42\r\nSupport me on PayPal: https://paypal.me/ArneSchmitz\r\nSupport me on YouTube: https://www.youtube.com/channel/UCPjFa_UZBUDzdJTIEdyGjIQ/join\r\n",
